Hike of about one hour uphill from Cameron Lake car park to a small lake in a mountain pass. In some years, the path is clear by June, and in others it can be under snow in July.
Summit Lake is located east of Cameron Lake in Waterton Lakes National Park Alberta, Canada along the Alderson-Carthew trail. It lies in the pass between Mount Carthew and Mount Custer.
Beautiful glacial lake, with opportunity for canoe rentals in summer.
