Johnston Canyon is a canyon on Johnston Creek in Banff National Park (Alberta, Canada).
You can see and experience the canyon on the Johnston Canyon trail, a beautiful hiking trail over, through and along Johnston Canyon. In the canyon, the Johnston Canyon lower falls and upper falls are two beautiful waterfalls. Erosion in all its splendor!
Up and down to Johnston Canyon upper falls, the trail is about 5 km long. There is a (free) parking at the trailhead.
