Lake McArthur Hike in Yoho National Park

Last updated:

All you need is half a day to do the Lake McArthur hike, one of the true gems in the Lake O’Hara area of Yoho National Park. The lake itself isn’t that big – just 1.5 kilometres long but the sapphire blue colour will mesmerize you as will the setting. The lake is 85 metres deep and is responsible for the intense blue colour.

The Lake McArthur hike begins on the north side of the Le Relais shelter and is well signed. This is a popular area used as a bus stop and is not difficult to find.

Lake McArthur hike route description

Head out on a generally flat trail to reach the Elizabeth Parker Hut in under a kilometre. It’s owned by the Alpine Club of Canada. As a side note it’s very difficult to get a reservation and it’s done via an online lottery every fall.

From there make your way up, steeply at times to Schaffer Lake. Walk around the lake and pass the McArthur Cutoff junction on your right. If you take the left fork you begin climbing again on the McArthur High Level trail.

Once you’ve passed beyond the boulders you end up in very pretty alpine meadows. This is a place where flower enthusiasts might enjoy a copy of the pocket guide – Popular Wildflowers of Alberta and the Canadian Rockies.

Then it’s a short descent down to the lake. Unfortunately on the day I was there it wasn’t as beautiful as it would be under sunny skies. From the lake you can retrace your steps or continue on the McArthur Low Level trail which is what I chose to do.

An option on the Lake McArthur hike

We passed the intersection of the low and high level trails in 1.2 km and from there retraced our steps back to Schaffer Lake. At the lake you have the option of going back the same way you came up but we elected to hike the Big Larches and then past Mary Lake to return to the shelter.

Good to know

The Odaray Highline Trail is one that is accessed off of the McArthur Pass cutoff. This area is prime grizzly habitat and should be avoided if possible. They have voluntary restrictions in place.

The hike to the lake is a total of 6.3 km with 413 m of elevation gain and will likely take you no more than a few hours.

Planning your hikes in the Lake O’Hara area

Doing any hike at all in the Lake O’Hara region takes some planning. If you’re thinking about camping the following is important as the rules in 2021 changed. 

All camping reservations at Lake O’Hara will now be offered on the Parks Canada Reservation Service beginning 8 AM MST in April 2021. Camping is possible from mid-June through until early October. Be warned, it can snow at any time. Nights can be very cold – early and late in the season.

How to get a seat on the bus to Lake O’Hara (if you just want to do a day hike)

As of 2021 the rules for booking buses have also changed in Yoho National Park.

This is what the park now says “All day use reservations for the Lake O’Hara shuttle bus will be booked through a random draw reservation system beginning in 2020. This system will improve the reservation service for visitors, reduce stress on the current reservation system, and help to ensure all online users have a chance at securing a reservation for a seat on the Lake O’Hara bus.

Now you must submit an application between February 1 -28, 2021 with a non-refundable $10 fee per application. Each application allows you to pick 6 different days and up to 6 bus seats. Applications will be drawn at random. If you get chosen you’ll have a two week time frame to respond or your seats will open up.
