It’s safe to say that all lakes in Banff/Yoho have mountains associated with them. But the mountains that surround Lake O’Hara take it to a whole new level. The lake is surrounded by an amphitheater of mountains on three sides. Even better, these three mountains have a trail that is continuous across all of them. This alpine circuit for hikers is the gift that keeps on giving. It’s well marked and above the treeline, so the views are exceptional. Above all, because only a handful of people can reserve either lodging or camping, it can feel like you are the only people there with the circuit all to yourself. Difficult to get to because of restricted access but well worth the effort of calling 3 months in advance so you can be one of the few with accommodations and thus access to this hiking playground.
