Cairn Pass is a backcountry tent campsite in Alberta managed by Parks Canada. Located along the South Boundary Trail in Jasper National Park, this site serves hikers traversing remote wilderness terrain. As a backcountry facility, campers should be prepared for primitive conditions without services or developed amenities. A valid national park camping permit and entry pass are required, and reservations must be made through Parks Canada before arriving. Given the backcountry location, visitors should be self-sufficient with proper equipment, navigation skills, and bear safety knowledge.
