As Johnston Creek approaches the Bow River, it flows through a large canyon formed by erosion over thousands of years. The creek has cut through the limestone rock to form sheer canyon walls, as well as waterfalls, tunnels, and pools.
A popular hiking trail follows the canyon and leads to a meadow within the Johnston Valley above the canyon. The first part of the trail consists of a constructed walkway with safety rails and bridges, while the last part of the trail is natural and more rugged. Within the meadow are the Ink Pots, which are six blue-green spring-fed pools. In August 2018, a few of the “natural” trails near the falls were closed off, in an attempt to help recover the small nesting population of the American black swift.[1]
Ice climbing is a popular activity on the frozen waterfalls in winter.
A tourist lodge and large parking area is located at the foot of the canyon, close to the creek mouth, along the Bow Valley Parkway (Highway 1A).
