Mount Assiniboine Provincial Park, Provincial nature reserve in British Columbia, Canada

Mount Assiniboine Provincial Park is a nature reserve in British Columbia spanning over 39,000 hectares of alpine lakes, glaciated peaks, and wildflower meadows. Elevations throughout the park reach up to 3,618 meters, creating distinct zones with varied vegetation and landscape character.

The protected area was established in 1922 following advocacy by the Alpine Club of Canada. Its boundaries were expanded in 1973 to encompass more of the surrounding alpine landscape.

The area remains significant for several Indigenous nations including the Ktunaxa, Peigans, Assiniboines, Blackfoot, and Kootenai, who historically traversed these mountain passages for trade and seasonal movement. Visitors who hike the trails today follow routes that have held meaning for these communities for centuries.

Access is only by foot via marked trails or by scheduled helicopter flights from Canmore, since no roads enter the protected area. Visitors should prepare for alpine terrain and be ready for rapidly changing weather conditions at high elevations.

The park's name comes from the Assiniboine, one of the Indigenous peoples who crossed the Rockies through these passes for trade. The mountain was first recorded in 1845 by Jesuit priest Pierre-Jean De Smet, who compared its rock architecture to the pyramids of Cheops and Chephren.
