Canadian Rockies 2025: Lake O'Hara, Part One

On July 20, 2025, Joan and I began our stay at Lake O'Hara. We boarded the lodge bus for the 11 km drive up the fire road to the lodge -- no private vehicles or bicycles allowed. After checking in, we started hiking towards Lake Oesa. This was the view from the south shore of O'Hara, with some cabins and the Opabin plateau centered in the frame.

At this time of year and altitude, the yellow columbine was in bloom. Lakeshore altitude: 2,020 meters (6,630 ft).

We soon began the switchbacks and other climbs towards Oesa. This cascade

was the exit for the smaller Victoria Lake along the way.

We'd encountered three light rain showers already and decided to turn around, find our now-available cabin, and unpack. At Yukness Lake,

we observed a browsing marmot.

The low clouds lingered as we left the marmot to his foraging.

Then it was downhill to Lake O'Hara, our cabin, and unpacking.

 

The next day, July 21, Joan and I set our sights on Lake McArthur. A 60% chance of showers was predicted for today, but the rain never came! Early on, we took a short spur from the main trail to visit Mary Lake.

Then we climbed the "staircase," a series of steps and switchbacks on the edge of a talus slope. In this photo, we're partway up, looking back at the Lake O'Hara basin.

Half an hour further along, hiking laterally for the moment, we encountered this hermit thrush.

Very close to this clump of alpine/rosy paintbrush.

We examined the sign-in kiosk for crossing the McArthur gap to the Odaray Highline, out of curiosity -- already the maximum of four parties had signed in. Joan and I took  the McArthur Highline trail,

and eventually crested with a view of McArthur. We were surprised to see very few people there.

As we walked down towards a good lunch spot, we attracted wildlife, including an inquisitive squirrel.

As we ate, we heard a loon call multiple times, and later spotted it! After rest and replenishment, Joan and I wandered down to the lakeshore.

Here's the signpost by which we measure the lake's level; this year, it's a smidge low.

We began our return on the low-level trail, which merges with the high-level trail at a saddle.

The low-level dives into the trees.

Moss campion was blooming!

Marmots were active here, some not too bashful.

Joan and I made a side trip on our return since it was still only 2:30. We took an "alpine" route to a viewpoint partway up the All Souls Prospect trail. This path was dodgier than non-alpine routes in terms of footing, steepness, and high steps, but it offers great views. It gave us a great sense of accomplishment, training, and hope that we could tackle other demanding hikes during our visit. Here's a panoramic take. Some haze has built up, but it's still beautiful.

It was a long but rewarding hike.
