As part of a peaceful and relaxing solo hiking trip to the Lake O’Hara region in 2010, I scrambled up Mount Schaffer early in the day on the 30th of September in perfect weather conditions. After checking out McArthur Lake (stunning) I had the rest of the day to explore part of the so-called Lake O’Hara Alpine Circuit, a gorgeous series of trails staring near the Lake O’Hara lodge and working its way up past Mary and Moor Lakes to Hungabee and Opabin Lakes before looping back around the upper Opabin Plateau and along Yukness Mountain’s south and west flank towards Lake Oesa. From Oesa the route traverses under the south face of Mount Huber and back down to Lake O’Hara from the Wiwaxy / Huber col, finally ending again at the lodge, or the Elizabeth Parker ACC Hut where I was staying for a few nights.

For the first day, since I had already done Schaffer Mountain and McArthur Lake, I was going to only do the All Souls Prospect and part of the Opabin Plateau circuit. The following day I would go back to Opabin Pass at the extreme eastern edge of the Lake O’Hara region before coming back around the Alpine Circuit near Lake Oesa and finishing with a scramble of Wiwaxy Peak – East. It was around mid day when I got back from McArthur Lake and started the steep grunt up All Souls Prospect from near the lovely Schaffer Lake which sits between Mount Schaffer and Mount Odaray.

The trail is well marked and obvious to the summit of All Souls. Being an alpine route, it is a fairly steep grunt with minor exposure in places. Once I started getting above tree line the views of the Lake O’Hara region were stunning in every direction. The crisp, clean and clear fall air conspired with the warm sun and sublime mountain views to give me one of the absolute best hiking experiences of my life. A very special day that will never leave me as long as I have memories.

One of my absolute favorite views from the entire day. From L to R, Mount Owen, Schaffer Lake, Walter Feuz, Odaray, Steven and Cathedral.

As I neared the summit of All Souls, I knew that this was going to be a very special day. The views of Lakes Mary and O’Hara directly under the prospect, combined with the Moor, Hungabee and Opabin Lakes and giant 11,000 foot peaks guarding the sparkling aqua gems and yellow larches below were mind blowing. This hike is clear proof that it’s not only mountaineers who can enjoy incredible mountain vistas. I spent an hour at the All Souls summit, relaxing with a coffee and taking panoramas of the views. If you’re OK with exposure, I recommend stepping just off the summit towards Lake O’Hara for a better view down to Mary and O’Hara lakes. Just don’t slip! 😉

Views over the core Lake O’Hara region include (L to R), Walter Feuz, Odaray, Stephen, Cathedral, Wiwaxy, Victoria, Huber, Lefroy, Glacier, Yukness, Ringrose and Hungabee. Schaffer Lake at lower left, Lake O’Hara at center and the Opabin Plateau at right.

It was tough to leave the beautiful summit of All Souls, but there was a lot of hiking and exploring left for me to do before dark so I started down the scree trail towards the Opabin Plateau far below. This trail is the most rugged part of the Lake O’Hara Circuit. I would recommend doing the circuit in the same direction I did, simply because you’ll take advantage of good lighting in the morning and you’ll descend the loose scree rather than grunt up it. Hikers not used to the alpine might find this section a bit unnerving – hiking poles will help your confidence immensely!

The Opabin Plateau has many hidden gems.

There are some options when descending to the Opabin Plateau. I choose some off-trail hiking near some nice running water and small falls in order to take late afternoon / evening photographs.

Huber, Lefroy, Yukness, Hungabee and Biddle reflect in Lake O’Hara.

I also chose to hike past the lovely Cascade and Moor Lakes before descending to Lake O’Hara and walking the shoreline in growing darkness.
