Marble Canyon Campground is the smallest vehicle-accessible campground in Kootenay National Park, with just 60 sites. Located in the northern section of the park, it is well placed for great hiking trails (Marble Canyon, Stanley Glacier, Paint Pots) as well as destinations in Banff National Park.
All sites become reservable in January via the Parks Canada website.
A Parks Canada parks pass is required to explore Kootenay National Park ($22/day for a vehicle of up to 7 people).
