Lake O’Hara Alpine Circuit: 2025 Hiking Guide

The Lake O’Hara Alpine Circuit is a truly spectacular high elevation hiking experience in Yoho National Park.

This 11km loop trail offers a highlights reel of the Lake O’Hara area, one of the Canadian Rockies most beautiful alpine landscapes.

Offering an awe-inspiring hiking adventure from beginning to end, the Lake O’Hara Alpine Circuit easily earns its place on my list of all time favourite BC hikes.

Turquoise lakes, huge mountain peaks, waterfalls, pine forest, alpine meadows…it’s all here and much, much more!

JR and I hiked the Lake O’Hara Alpine Circuit in late September 2024, on our second visit to the area and during the height of golden larch season.

Lake Oesa and Lefroy Lake (Yukness Ledges)

In this post, I’ll share what you need to know about hiking the Lake O’Hara Alpine Circuit including what to expect, when to go, essential items to bring and which direction to hike. I’ll also suggest how to explore just one section of the Alpine Circuit.

The Lake O’Hara Alpine Circuit

The Lake O’Hara Alpine Circuit is situated in Yoho National Park, British Columbia, Canada. Yoho National Park borders the much more famous Banff National Park.

Lake O’Hara is a beautiful alpine area on the eastern edge of Yoho, featuring turquoise lakes, waterfalls, huge mountain peaks, several glaciers, hanging valleys and more. Head to our Lake O’Hara guide for all the general details!

The 11km Alpine Circuit showcases the best of Lake O’Hara, including Lake Oesa and the Opabin Plateau. Panoramic views are offered almost the entire way along, making this hike a real feast of alpine imagery.

The Alpine Circuit is a combination of easy hiking trails and three more difficult alpine routes:

  • Wiwaxy Gap/Huber Ledges
  • Yukness Ledges
  • All Soul’s Route
Odaray Mountain as seen from the Yukness Ledges

These alpine routes traverse high elevation terrain. Some sections feature rock slabs, ledges, scree slopes (small rocks) and talus (large boulders). Route finding is less obvious in these areas and careful footing is important.

Needless to say, the Alpine Circuit is not the ideal destination for anyone with a fear of heights. But it is more approachable than you may think.

Since the Alpine Circuit is a blend of trails, each section is individually accessible so you don’t necessarily have to hike the entire Alpine Circuit in one go. But if you can, do it all! This is a hiking experience like no other in British Columbia.

Lake O’Hara is located on the traditional lands of the Ktunaxa and Shuswap First Nations as well as the Niitsitapi, Michif Piyii (Métis), Tsuut’ina and Ĩyãħé Nakón mąkóce (Stoney). Quite a few of the mountain peaks retain Stoney names.

Quick facts

  • 11km circuit hike with just over 1000m elevation gain
  • Officially starts and finishes at Le Relais Shelter
  • Best time to hike is late July to mid/late September
  • Most often hiked in a clockwise direction
  • Trail is entirely above 2000m elevation
  • Low side of challenging difficulty
  • Accessible via shuttle bus or 11km (22km return) access road only

Alpine Circuit trail difficulty

The Alpine Circuit’s beauty is legendary. But how hard is it to hike?

For me, Lake O’Hara’s Alpine Circuit is on the low side of difficult/challenging. Here are a few reasons why.

There is some exposure along the alpine route sections, meaning that there is a high risk of injury when falling in these areas. Think steep drop-offs, a narrow trail and slippery cliff edges. Careful footing is required in many places.

There are several steep climbs and descents with slippery loose rock, in very high alpine areas (2000m+). While much of the Alpine Circuit follows an established path, there are rocky sections that require some route finding.

There is very little shade or shelter on most of the trail so hikers do not have any protection from sun, snow, rain or wind.

Hiking the Alpine Circuit in wet or snowy weather would certainly be more hazardous due to the amount of steep drop-offs and amount of slippery surfaces.

The length of the Alpine Circuit isn’t extraordinarily long but it does have over 1000m of elevation gain and a similar amount of loss. This can be tiring, especially if you’re not used to it.

The Wiwaxy Gap part of the Alpine Circuit can be seen above – look for the tiny trail on the right hand side of the photo, running diagonal to the avalanche chutes

Is the Alpine Circuit right for you?

Having said all of this, I think the Lake O’Hara Alpine Circuit looks and sounds more intimidating than it is (unless you are truly afraid of heights!)

While it is still not a trail to take lightly, especially during the early/late season and in inclement weather, I think most folks who have experience with long alpine day hikes (15km+ with 700m or more elevation gain) will find it manageable.

For context, I don’t enjoy narrow trails with big drop-offs. I wasn’t sure how I’d like the Alpine Circuit but I was fine. Any places I felt were a little narrow for my liking were over pretty quickly.

One great aspect of the Alpine Circuit is that you can try a section and then turn around or exit at the next trail junction if needed. Lake O’Hara’s extensive trail network makes it very easy to navigate to a less difficult trail.

An easy one to try would be the Yukness Ledges – approach it from either direction and see how you go. Be careful not to get lost in the first boulderfield. There are great views from the beginning of either side.

As a side note, I have suggested 5 to 8 hours to hike the Alpine Circuit. It is a very, very beautiful hike so don’t feel rushed – if you have the time, plan to spend as long as you can. 5 hours doesn’t allow for many photo stops or extended breaks.

We spent 8 hours on the Alpine Circuit but, honestly, we would have been happy to stay longer if not for the cooler weather in late September!

The Alpine Circuit has so many photogenic spots

The Lake O’Hara Alpine Circuit is featured on our favourite offline navigation app, Organic Maps. We found the marked route to be accurate.

Note that all three Alpine Circuit sections are named individually on Organic Maps, rather than as the ‘Alpine Circuit.’

The Alpine Circuit is very well signed, with Parks Canada trail markers at every junction.

The path of the Alpine Circuit is well established, with a clear dirt trail through forest and meadow areas. It is narrow in places and never very wide.

In rocky areas, the trail is marked with cairns (rock towers) and blue and yellow alpine route symbols painted on rocks. These appear at least every ten metres through sections with boulders and ledges.

The best time to hike the Alpine Circuit

The best time to hike the Alpine Circuit is late July to late September.

It is may be possible to hike the Circuit earlier or later in the season but it is completely weather dependent.

The ledges and narrow sections are more dangerous when snow and ice covers the trail.

To add to that, the alpine route sections travel through avalanche areas. Early season closures for avalanche hazard are possible – this was the case on our first visit to Lake O’Hara in mid July 2020.

Lake O’Hara Alpine Circuit views in late September

Late September is, in my opinion, the most beautiful time to hike the Alpine Circuit.

There are several larch tree forests in the Lake O’Hara area. In late September, the needles of the trees turn bright yellow before dropping for the winter.

The golden glow combined with the snow dusted mountain peaks and turquoise lakes is an extraordinary sight.

We hiked the Alpine Circuit on 28th September 2024, when the larch were at their golden peak. This usually lasts around 7-10 days.

Some years, there is snow on the trail at this time. A few days after our hike, most of the route was covered by snow in the morning, before the sun melted it at lower elevations.

The Opabin Plateau is one of my favourite places anywhere in the Canadian Rockies!

Which direction to hike the Lake O’Hara Alpine Circuit

The Lake O’Hara Alpine Circuit can be hiked in either a clockwise or counterclockwise direction. The most common direction is clockwise for a number of reasons.

For one, the climb up to Wiwaxy Gap is the highest and longest. A lot of people like to get that over and done with early.

The trail builders apparently built the route to be hiked clockwise. To add to that, the light is better for photography when hiking clockwise in summer.

Personally, I liked that most people were hiking the Alpine Circuit clockwise. It meant that we didn’t meet that many people travelling in the other direction.

It made for a quieter hike overall and meant we didn’t have to cross paths with hikers when traversing narrow sections.

Having said all of that, I know quite a few folks who enjoyed their counter clockwise hike.

The approach to Wiwaxy Gap from the other direction is a lot more gradual, even if it does mean a long, steep descent down to Lake O’Hara. The steepest climb in this direction would be up to All Soul’s, which is relatively short compared to Wiwaxy Gap.

Regarding the light preference for the clockwise direction, I found that it didn’t really benefit our late season hike.

Due to the short September days, we were in shade after leaving the Opabin Plateau for All Soul’s. Had we hiked counterclockwise, we would have not have been in shadow on Wiwaxy Gap.

How to get to Lake O’Hara

The Alpine Circuit starts next to Lake O’Hara, which is 11km from the Lake O’Hara parking lot next to Highway 1 in Yoho National Park (Google Map directions).

There are five ways to access Lake O’Hara from the parking lot:

  • Visit for the day by bus – Enter a lottery to reserve a seat on the Parks Canada Shuttle Bus
  • Visit for the day by foot – Hike 11km up the access road and then try to secure a bus seat out or hike 11km back
  • Camp for up to three nights – Reserve a tent site at the Lake O’Hara campground, shuttle bus ride included
  • Stay at the Lake O’Hara Lodge – Reserve a cabin or lodge room at this historic lodge situated right on the shores of Lake O’Hara, private shuttle ride included
  • Stay at the Elizabeth Parker Hut – Reserve a bed at this rustic backcountry hut near Lake O’Hara, shuttle bus ride included.

I explain each of these options in more detail in our Lake O’Hara Hiking and Camping guide. As you can see, however, a reservation is essential for all five methods.

If you don’t manage to secure a reservation (or are reading this too late!), I’d suggest checking often for cancellations. Alternatively, you can let a cancellation service like CampNab to do the hard work for you.

Looking back towards Lefroy Lake and Lake Oesa on the Yukness Ledges section

The Lake O’Hara Shuttle bus

The Lake O’Hara Parks Canada Shuttle Bus transports 120+ hikers into Lake O’Hara each day. About half of those will be staying overnight at the campground or Elizabeth Parker Hut.

The remaining seats are allocated in the day shuttle bus lottery, which occurs in early spring each year (3rd to 24th March in 2025). Hikers are allocated a specific bus for the journey into Lake O’Hara.

Ingoing (to Lake O’Hara)Outgoing (to the parking lot)
8.30am9.30am
10.30am11.30am
3.30pm*2.30pm
5.30pm*4.30pm
6.30pm
*For overnight guests only (no day hikers)

Hikers who don’t have a bus reservation can always make their own way to Lake O’Hara on foot along the access road (option 2). Bikes are not allowed.

The access road features 450m elevation gain over 11km and takes around 2-3 hours to hike. The road is not a very exciting hike (trust me, I’ve done it in both directions) but it is straightforward and gets you there.

Keep in mind, however, that combining hiking the access road with the Alpine Circuit makes for a very long and challenging day. It’s easier for trail runners.

There is the possibility of securing a spot on an outgoing bus service. Shuttle bus lottery ‘winners’ and campers always have priority.

Wait outside the Le Relais Shelter at the appropriate time and the Parks Canada staff will allocate you a seat if there is space. The cost is $15/person (cash only).

For the best chance to get a spot, try for the 4.30pm service. There are two buses departing at this time.

Note that you’ll need an early start (potentially 8am or earlier, depending on your hiking speed and ability) to be able to hike the access road and complete the Alpine Circuit in time for the 4.30pm bus.

Lake O’Hara Alpine Circuit Hiking Experience

Wondering what to expect when hiking the Lake O’Hara Alpine Circuit?

This part of the guide breaks the hike down with an overview of each route section.

I have also suggested ways to extend the Alpine Circuit (for hikers wanting a longer experience) and how it is possible to hike each section individually (for hikers wanting a shorter experience).

The Alpine Circuit starts and ends at the Le Relais Shelter near Lake O’Hara. This information centre/cafe is also the main Lake O’Hara shuttle bus stop. There are a couple of outhouses here but no others on the Alpine Circuit.

I will describe the route clockwise, the most popular direction.

Lake O’Hara’s Le Relais Shelter

Wiwaxy Gap/Huber Ledges

Distance: 3.2km
Elevation gain/loss:
570m/300m
Difficulty:
Challenging, allow up to 3 hours

The Wiwaxy Gap/Huber Ledges section is, in my opinion, the most intimidating of the Alpine Circuit. From afar, it looks so gnarly! It is far more approachable when on the actual trail.

From the Le Relais Shelter, join the Shoreline Trail and head west, over the bridge. Turn right after the bridge.

In just a few minutes you’ll reach the Wiwaxy Gap Alpine Route junction (360m total from Le Relais).

A small dirt trail leads uphill from the camera below a rock cliff. The path is very narrow with a steep drop off to the right hand side
One of the most exposed stretches of the trail up to Wiwaxy Gap

From here, it is up, up and up on short switchbacks through an avalanche chute.

The switchbacks help gain elevation fast – it’s a work out but there are incredible views of Lake O’Hara almost immediately.

Around 500m in, the trail straightens out and heads below a cliff. The path becomes narrower and there is a slope on one side (see above photo).

Lake O’Hara views from the trail to Wiwaxy Gap
Rocky steps on the way to Wiwaxy Gap

Soon after, there is a series of rocky steps – look for the yellow and blue painted markers (above photo)

The rest of the climb traverses a dirt path across a scree slope, with some longer switchbacks. It’s a bit of a grind but one a very scenic one.

The final approach to Wiwaxy Gap features long switchbacks

At the top is Wiwaxy Gap, a great place to take a break and take in the views of the back of the Wiwaxy peaks.

The descent to Lake Oesa is gradual, with the trail travelling along cliff bands below Mount Huber. This is the Huber Ledges.

Wiwaxy Gap view looking towards the Huber Ledges

The path is quite narrow with a slope on one side, but it isn’t a sheer drop.

There are some slabby sections (again, look for the yellow and blue markers) and a few areas with small loose rocks. Hiking poles can be helpful here.

Traversing the Huber Ledges after Wiwaxy Gap
Heading downhill to Lake Oesa

While admiring the views of Lake Oesa and Glacier Peak behind it, look for the much smaller icy blue Lefroy Lake.

The trail ends close to Lake Oesa – turn right to head towards the shoreline. This is another good place for a break (and get water if you need it). The Lake Oesa trail transition is 360m long.

Lake Oesa

Yukness Ledges

Distance: 2.4km
Elevation gain/loss:
230m/250m
Difficulty:
Moderate, allow up to 2 hours

The easiest of the three alpine routes is the Yukness Ledges. It still has some narrow areas with steep drops but the elevation gain is far less than the other two. It also has my favourite view!

To re-join the Alpine Circuit, look for the Yukness Ledges trailhead near Lake Oesa’s outlet, on its western side.

The start of the Yukness Ledges alpine route is partially hidden behind cliffs

It can be tricky to see as there are lots of rock slabs around the lake and the path drops behind some cliffs (above photo).

After reaching the river, the trail slowly climbs along the base of Yukness Mountain. The first section features a dirt path across a scree slope, which transitions into a less obvious route through a boulderfield.

Scree slope at the start of the Yukness Ledges
First boulderfield section along Yukness Ledges

Look for the blue and yellow markers to stay on track as it would be easy to get lost in this area.

Some of the boulders are pretty big and you may need to use your hands to get down and around them.

Start of the Huber Ledges – note the painted alpine route marker on left

Stay left at the trail junction and the ledges part of the trail begins. The first rock ledges are fairly wide, which soon become narrower.

The ledges are connected by short up-down trail sections, which are steep at times with some loose rock.

There is a slope on one side, which is precipitous in a couple of places. This section appears a lot more scary in photos.

One of the more perilous looking Huber Ledges

The amazing views of Lake O’Hara offer an excellent distraction!

As the path eventually turns the corner and starts travelling away from Lake O’Hara, it becomes much more like a regular hiking trail.

My favourite view on the Alpine Circuit!

Heading slowly downhill, expect to see wonderful views of the Opabin Plateau, a beautiful hanging valley filled with larch trees.

Close to the end, a boulderfield swallows up the trail. Again, look for the blue and yellow markers for the best route through the large rocks.

The easiest Yukness Ledges stretch is an ordinary hiking trail
The Yukness Ledges route ends with a boulderfield

Back on the regular trail, follow the signs to the All Soul’s Route or detour via Opabin Lake or the Opabin Prospect (both described below).

The Opabin Plateau is a glorious place to explore – think lush meadows, lakes, creeks and huge peaks. The direct route to All Soul’s is 1.2km.

Looking across Opabin Plateau, a subalpine region surrounded by mountains and dotted with golden larch trees
Opabin Plateau in late September

All Soul’s Route

Distance: 2.1km
Elevation gain/loss:
230m/280m
Difficulty:
Challenging, allow up to 2.5 hours

The All Soul’s Route is the final section of the Alpine Circuit. I find it a bit of a ‘short and sweet’ experience, albeit with a bracing climb!

The route originates from a junction on the West Opabin Trail, near the Opabin Prospect. The beginning is rocky, with several sets of slab staircases.

Starting the All Soul’s Route

The path then traverses the top of a wide cliff. There are some excellent views of Mary Lake and Lake O’Hara from here.

A few more rocky sections and the trail transitions to an established gravel path, which travels up and across a scree slope. The trail is quite narrow, with a drop-off on one side.

Views of Mary Lake and Lake O’Hara from the start of the All Soul’s Route

The ascent is relatively gradual for the most part, with some steeper sections near the end.

This area is in shade for most of the day so ice and snow during the early/late seasons will linger here longer than other sections of the Alpine Circuit.

The All Soul’s Prospect ascent is steady but offers great views
The final approach to All Soul’s Prospect is quite steep

The All Soul’s Prospect is the highest point of this alpine route. There is a large viewpoint area offering stunning panoramas of Lake O’Hara, the Opabin Plateau, Schaffer Lake, McArthur Pass and many surrounding peaks.

Lake O’Hara from the All Soul’s Prospect

The descent from All Soul’s Prospect is immediate and very steep. There are some tight switchbacks and loose rock. Again, look for the blue and yellow markers.

Be careful with your footing – for balance and also to avoid disturbing too many rocks. The steepest part is at the beginning (first 200m). I used a hiking pole here.

Descending All Soul’s Prospect – the first section is very steep

Eventually, the trail flattens out just above Schaffer Lake. The quickest route back to the Le Relais Shelter is via the Alpine Meadows Trail (1.4km).

This mostly downhill path passes the Elizabeth Parker Hut.

During golden larch season in late September, I’d recommend detouring via the Big Larches Trail instead. The route is just slightly longer and less of a straightforward walk (rockier surface) but the larch are spectacular to see.

Lake Schaffer and McArthur Pass are both visible when descending All Soul’s Prospect

Alpine Circuit extension options

There are so many ways you could extend the Lake O’Hara Alpine Circuit. Here are some ideas for short (30 minute) and longer (1.5 to 2 hours) add-on hikes.

Opabin Prospect

Distance: 800m detour loop from Alpine Circuit
Elevation gain:
20m
Difficulty:
Easy

The Opabin Prospect is a rocky cliff at the edge of the Opabin Plateau that offers offers incredible views across Lake O’Hara and Mary Lake. It is the most well known panorama in the Lake O’Hara area.

For many people, a detour to the Opabin Prospect is a must while hiking the Lake O’Hara Alpine Circuit. It doesn’t add much mileage and the payoff is high. We enjoyed a late lunch on the Prospect’s wide rock slabs.

After completing the Yukness Ledges section, you’ll arrive onto the Opabin Plateau. Follow the signage to the continuation of the Alpine Circuit, to All Soul’s Route.

Near the Cascade Lakes (about 800m from the Yukness exit), there is a junction with a turn for the Prospect.

If you don’t see it, there will be another chance further on but you’ll miss the chance to hike a loop. By this point, it’s easier to do an out-and-back.

Lake O’Hara’s most famous viewpoint – Opabin Prospect

Opabin Lake

Distance: 1.3km loop detour from Alpine Circuit route
Elevation gain:
50m
Difficulty:
Easy

Opabin Lake sits at the end of the Opabin Plateau hanging valley, backdropped by a glacier and Yukness Mountain. It’s a spectacular sight and an easy add-on to the Alpine Circuit.

After completing the Yukness Ledges section, you’ll arrive onto the Opabin Plateau. Turn left and head towards the back (southeast) of the valley. Opabin Lake is only 350m up this trail.

The quickest way to return to the Alpine Circuit is to simply turn around. But I’d recommend hanging right, continuing along the trail in front of the lake and then follow a loop route back (only around 600m extra). There is signage at every trail junction.

Opabin Lake in mid July

Lake McArthur Circuit

Distance: 3.2km detour loop from Alpine Circuit
Elevation gain:
180m
Difficulty:
Low side of moderate

Lake McArthur is a glorious sapphire blue-coloured lake backdropped by huge peaks and a glacier. Some people find Lake McArthur to be more beautiful than Lake O’Hara.

Personally, I think this lake is spectacular in its own right. I think that the deep blue colour is truly mesmerising! We were lucky to spot mountain goats here.

There are two trails leading to Lake McArthur – a high path and a low path. I’d recommend combining them into a loop; either direction is fine.

If you only have one day in Lake O’Hara and the stamina to combine both the Alpine Circuit and Lake McArthur, you can leave knowing you would have seen all of the ‘major’ sights.

Lake McArthur on a snowy early fall day

Odaray Grandview

Distance: 3.6km return + 1km detour from Alpine Circuit
Elevation gain:
320m
Difficulty:
Moderate

Strong hikers may consider adding the Odaray Grandview to their Alpine Circuit hike. It also features an alpine route section, high above the treeline.

As the name implies, the Odaray Grandview features an absolutely extraordinary panorama of the entire Lake O’Hara area (seriously, it’s really good). The full Alpine Circuit can be seen in all its glory as well as nearby Lake McArthur.

Since the Odaray Highline runs through a crucial wildlife corridor, there is a voluntary program to reduce access. Only a limited number of hiking groups are should use the trail each day.

With that in mind, it makes more sense to attempt to hike the Odaray Grandview before heading to the Alpine Circuit. The trailhead is 530m from Schaffer Lake, near the All Soul’s Prospect section.

Odaray Grandview – this is my top pick for Lake O’Hara’s best view

Section hiking the Alpine Circuit

All three Alpine Circuit sections are individually accessible so you don’t necessarily have to hike the entire Alpine Circuit in one go.

If time, weather or trail conditions aren’t favourable, consider hiking just one part of the circuit. This is also a good option if you’re not comfortable about tackling the whole thing in one go.

In my opinion, the easiest and most approachable Alpine Circuit section is the Yukness Ledges. The ascent is less steep, there are only a few narrow parts and it just feels less high.

If you have the time to hike two sections of the Alpine Circuit, my vote would be for a combination of the Wiwaxy Gap/Huber Ledges and Yukness Ledges. I think this stretch showcases the best views overall.

Lake O’Hara as seen from the Yukness Ledges

Wiwaxy Gap/Huber Ledges

Follow the Lake O’Hara Shoreline Trail to the Wixwaxy Gap trailhead. After reaching Lake Oesa via the Huber Ledges, return to Lake O’Hara via the Lake Oesa Trail.

The total distance would be around 6.5km with 650m elevation gain.

Lake Oesa from the Huber Ledges

Yukness Ledges

Follow the Lake O’Hara Shoreline Trail to the Lake Oesa trailhead.

Join the Alpine Circuit at Lake Oesa and then exit on the West Opabin Trail with an optional detour to the Opabin Plateau. Complete a circuit by finishing on the Shoreline Trail.

The total distance would be around 9km, including the Opabin Plateau detour (extra 800m). Total elevation gain – around 610m.

Opabin Plateau creek

All Soul’s Route

Follow the Lake O’Hara Shoreline Trail to the West Opabin Trail. Join the Alpine Circuit near the top of the climb or detour to the Opabin Plateau for the views first.

After finishing All Soul’s, return to the lake via the Alpine Meadows Trail or the slightly longer Big Larches Trail.

The total distance would be around 6.2km (with around 500m elevation gain) including the detour to the Opabin Plateau.

Lake O’Hara Alpine Circuit Essentials

Ready to go hike the Lake O’Hara Alpine Circuit? Keep the following in mind!

Safety tips

  • Lake O’Hara is located is a remote high elevation mountainous area with no phone signal
  • Weather conditions can change quickly and often in this area – snow is possible at any time of year
  • Be sure to tell someone where you are going and when you’re coming back
  • Due to the limited access, Lake O’Hara is quieter than other popular areas in the Canadian Rockies (fewer other hikers)
  • For all of the above reasons, Lake O’Hara hikers must be self reliant and carry everything they need, including food, water, clothing and First Aid supplies
  • Dogs are technically allowed on the Alpine Circuit but keep in mind that the terrain may be difficult for them. Dogs are also not permitted on the Parks Canada shuttle bus
  • Careful footing is required in many areas on the Alpine Circuit. Take your time. Accidents are more likely to happen when rushing
  • Campers and day shuttle users – keep your green Lake O’Hara bus token in a safe place! It is your ticket out
  • Be sure to stay on the established trails while exploring Lake O’Hara – this reduces the risk of getting lost and also helps avoid damage to the fragile alpine landscape
  • Pack out everything you bring to keep Lake O’Hara beautiful!
Yukness Lake and Lake O’Hara from the Yukness Ledges

Must have items

Grizzly bears live in the Lake O’Hara area so I’d strongly recommend bringing bear spray. Keep it handy in a holster and know how to use it. More information and tips in our bear safety guide.

As mentioned, the weather can change quickly and often around Lake O’Hara. Bring plenty of warm layers, even during the warmer months (merino wool layers are our fave).

I never hike in the alpine without a waterproof rain jacket in my backpack.

Extra clothing is just one of the 10 essentials for outdoor adventure.

Other items include a light source (headlamp), sun protection (sunscreen/sun hat), a map, food, First Aid supplies and an emergency shelter. For the latter, an emergency blanket is a lightweight solution.

A warm hat, gloves and a neck gaiter (Buff) are a must in case of cold wind.

Yukness Ledges Alpine Route signage

Hiking poles are a great item to have while hiking the Lake O’Hara Alpine Circuit.

There are some steep sections with loose rock – hiking poles can be helpful for balance and to reduce knee pressure. We love Black Diamond’s super light Carbon Z poles.

Be careful to carry enough water, especially during the warmer months. Bring a purification device so you can collect on the go and carry less. We use the very packable BeFree.

You’ll want to take a lot of photos while hiking the Alpine Circuit! If your phone is also your camera, bring a portable battery charger.

For emergencies, we like to carry an InReach satellite communication device.

If attempting the Alpine Circuit early or late in the season, I would bring microspikes for traction on snow and ice. We swear by Kahtoola Microspikes – I once scaled a super steep (65 degree) ice slope in them!

Opabin Plateau from the All Soul’s Route

Campground information

The Alpine Circuit is just one reason to visit Lake O’Hara. There are many more scenic trails to explore. If you can, try to camp at Lake O’Hara for three nights (the maximum allowed).

The Lake O’Hara Backcountry Campground is located in a forest, about 600m from the lakeshore. The campground is open mid-June to early October each year.

There are 30 semi-private, numbered tent pads and a large communal cooking area.

I have to say, this campground is pretty deluxe for a backcountry one , with facilities such as running water (!), two cooking shelters with wood stoves, a storage shelter and garbage bins.

Campsites at the Lake O’Hara campground must be reserved in advance via the Parks Canada Reservation System, online or by phone. Shuttle bus reservations are included with every campsite booking.

In 2025, campground reservations will open on 23rd January at 8am MST.

For more campground details and tips for securing a reservation, head to our dedicated Lake O’Hara Hiking and Camping guide.
