We visited Lake O'Hara on the last day of a 10-day trip around the Canadian Rockies. I can't believe this Lake isn't more talked about. It is at least as beautiful as Lake Louise, and because of limited access, hardly any tourists. There are tons of trails and several other lakes around and above Lake O'Hara. To get there, you either have to walk up the 8-mile road, or book your spot on one of the two buses that go there daily during the summer season. Normally to get a spot on the bus you have to book 3 months in advance, as there are only 2 buses of 35 people per day, or just 70 people at the lake (plus any campers or lodge guests) on any given day! We got very lucky and secured a spot for the six of us during the first week the road was open.
The only downside for us was that there was still quite a bit of snow at the upper elevations (3rd week of June) so we couldn't hike all the trails. But the Lake itself is pristine, surrounded by alpine forest, rocky outcroppings, snow-capped peaks, all reflected against the blue-green water. The photos came out so beautiful they look fake.
I would rate Lake O'Hara the #1 or #2 attraction in the Canadian Rockies, not to be missed.
