In a Nutshell..
The BC Rockies region of British Columbia is located in the southeastern corner of the province, bordering Alberta and the US state of Montana. The Rockies includes the area from Creston in the Selkirk Mountains to Cranbrook in the Purcell Mountains, the Crowsnest Pass and the British Columbia/Alberta border in the Rockies, and the Columbia River Valley from Cranbrook to Golden.
For outdoor enthusiasts, the route from Creston to Crowsnest Pass is a mother lode of serious adventure. The British Columbia/Alberta border parks - Height of the Rockies Provincial Park, Elk Lakes Provincial Park, and Akamina-Kishinena Recreation Area - present some truly extraordinary landscapes to explore.
The Rocky Mountain Trench (also known as the Columbia Valley) is surmounted by the Rocky Mountains on the east and the Bugaboos on the west. Both are impressively high and rugged ranges.
