The pass is located in southeast British Columbia and southwest Alberta, and is the southernmost rail and highway route through the Canadian Rockies. It is the lowest-elevation mountain pass in Canada south of the Yellowhead Pass (1,130 m (3,710 ft)); the other major passes, which are higher, being Kicking Horse Pass (1,640 m (5,380 ft)), Howse Pass (1,530 m (5,020 ft)) and Vermilion Pass (1,680 m (5,510 ft)).
Crowsnest Pass comprises a valley running east–west through Crowsnest Ridge. On the Alberta side, the Crowsnest River flows east from Crowsnest Lake, eventually draining into the Oldman River and ultimately reaching Hudson Bay via the Nelson River. Summit Lake on the British Columbia side drains via three intermediary creeks into the Elk River, which feeds into the Kootenay River, and finally into the Columbia River to the Pacific.
