Cahill Lake Campground provides backcountry camping access in Valhalla Provincial Park in British Columbia's Kootenay region. The trail to the lake is rated as hard, reflecting the challenging terrain of the Selkirk Mountains that the park was created to protect. As a backcountry site, campers should be prepared for wilderness conditions and pack accordingly. The campground serves hikers exploring the park's diverse topography and majestic mountain peaks. Those planning a visit should contact BC Parks to confirm current access conditions, camping regulations, and any applicable fees.
