Johnston Canyon

A path suspended on iron catwalks climbs through a limestone slot canyon, with the creek thundering a few metres below and mist hanging in the air. Johnston Canyon is one of the most popular short hikes in Banff National Park and the Canadian Rockies, and it earns the attention. The canyon lies on the Bow Valley Parkway, about 25 kilometres northwest of the town of Banff, and Johnston Creek has cut it deep into the limestone over thousands of years, leaving smooth, curved walls, pools of a vivid blue-green and a series of waterfalls.

The trail is paved or boardwalked in many places and is gentle enough for families. The route to the Lower Falls is roughly 1.2 kilometres each way, a walk of 20 to 30 minutes, and the catwalks bolted to the canyon walls bring you to a viewing platform right in front of the falls. A short tunnel through the rock leads to a closer view, where the spray can soak those who stand near. Beyond the Lower Falls the path climbs to the Upper Falls, about 2.7 kilometres from the trailhead, a taller cascade that tumbles about 30 metres into a pool. Farther on, a quieter trail leads to the Ink Pots, a group of mineral-coloured springs set in a meadow at the head of the canyon.

In winter, the canyon takes on another character. The falls freeze into columns of blue and white ice, and guided ice walks offer a chance to explore the frozen creek with cleats and a guide. At any time of year, the rock walls and rushing water make a striking backdrop for photographs. In summer, early morning and evening are far less crowded than midday, and in peak season the trail can be busy and the car park full.

Safety matters here. Stay on the trail and behind railings, as the creek is cold and fast. Bears and other wildlife live in the area, so carry bear spray and keep noise up. Check Parks Canada for closures, which can occur for maintenance or conditions, and consider using the shuttle service when it runs rather than driving. Wear sturdy footwear, since boards can be wet and slippery.

The canyon suits visitors of nearly every age, and a few hours is enough for the main falls.
