Johnston Canyon is a tributary of the Bow River in Banff National Park.
The canyon has been formed by erosion over thousands of years. The Johnston Creek, which empties into the Bow River, has cut through limestone rock creating the canyon.
Catwalks are attached to the limestone walls allowing visitors to follow the Johnston Creek through the canyon.
It is 1.1 km (1/2 mile) one way the the Lower Falls and 2.2 km (1 1/2 miles) one way to the Upper Falls. Allow 2 to 2/12 hours for a return trip to both the Lower and Upper Falls.
For a longer hike continue on 3 kms from the Upper Falls to the Ink Pots, a series of green coloured mineral pools.
At the lower falls you can cross a bridge and climb through a tunnel to see the waterfall up close. Expect to feel the spray from the waterfall and during busy periods you may have to wait to enter.
At the base of the trail is the Johnston Canyon Resort. There is a restaurant, gift shop and ice cream stand. The resort offers cabin and cottage accommodation.
Johnston Canyon is 25 km from Banff and 33 km from Lake Louise on the Bow Valley Parkway.
