Hamber Park forms part of one of the world's largest protected-area blocks and is included in the Canadian Rocky Mountains World Heritage Site. BC Parks describes it as a remote wilderness park with few facilities, centered on Fortress Lake.
The park is reached by a 22-kilometre route from the Sunwapta Falls trailhead in Jasper National Park to the campground at the east end of Fortress Lake.
Hamber Park is for experienced wilderness travellers who want remote lake country, mountain scenery, and serious self-reliance. BC Parks notes a rustic campground and toilet at the east end of Fortress Lake, an air-accessed commercial fishing camp on Chisel Creek Fan, and traditional campsites along the north shore.
Hiking is demanding. The old north-shore trail is open for hikers, but no other trails exist. Washout Creek offers steep, rugged access toward scenic alpine areas, while the approach from Sunwapta crosses both the Athabasca and Chaba rivers without bridges. BC Parks does not recommend fording the Athabasca River.
Fortress Lake is known for brook trout fishing and is also open for winter ice fishing, though the travel distance is substantial.
Plan around remote hiking, Fortress Lake camping, brook trout fishing, winter ice fishing, backcountry skiing, snowshoeing, climbing context in the Canadian Rockies, boat access through the fishing camp, and seasonal hunting where open.
Bring drinking water or be ready to boil or filter it. Expect rain and wind in summer, dangerous stream crossings, blowdown hazards, and bear-country precautions. Vehicles left at Sunwapta Falls require Parks Canada registration.
