Catwalks and Frozen CurtainsWalking Johnston Canyon in Banff

At first blush the trail is almost deceptively tame. From the small trailhead parking lot on the Bow Valley Parkway, the path begins as a mellow, well-graded boardwalk that moves through lodgepole pine and scrub spruce. Within 15–20 minutes the canyon edges close and the real show begins: a series of suspended walkways and bridges that thread between vertical walls, taking you to spray-soaked viewpoints over Lower and Upper Falls. The Lower Falls arrive first—an abrupt, thundering cascade framed by narrow walls—then the route continues, climbing into steeper, rockier terrain, and ultimately to the Upper Falls, where the water hurls itself off a collapsed cliff and explodes into a deep pool below.

Geologically, Johnston Canyon is a classroom. The canyon was carved by Johnston Creek over tens of thousands of years, slicing through Mississippian-age limestone and dolomite laid down when this region was a shallow sea. Layers of bedding and the occasional fossil trace are visible if you look close; freeze-thaw cycles and persistent glacial melt sculpt the waterfalls and smoothed alcoves that make the canyon so photogenic. Human hands have only made the route easier to read: the catwalks—installed to protect fragile habitat and to keep visitors off slippery rock—let you move through the canyon without trampling the creekside vegetation.

Culturally this land belongs to the Stoney Nakoda and other Indigenous nations whose territories predate the park. The broader Bow Valley was a travel corridor for millennia; later, the era of railway tourism and the founding of Banff National Park in 1885 brought organized exploration and the infrastructure that eventually formed the modern trails. Today the canyon sits squarely between conservation and access—one of the most-loved day hikes in the Canadian Rockies and, as a result, one of the most crowded. That popularity is part of its charm: the communal rhythm of families, photographers and hikers sharing a concise, visually intense experience.

Why go? Johnston Canyon is an efficient mountain hit: it delivers waterfalls, a dramatic limestone gorge and photogenic catwalks in a walk that most people can complete in a few hours. Beyond the obvious, the trail is a superb training ground—short, variable terrain and exposure to slick surfaces teach good footwork before you head into longer backcountry days. For winter travelers, the frozen falls are a different creature: icewalks through the canyon present surreal blue columns and delicate iced stalactites, while the approach requires microspikes or crampons and more careful footing. For hikers with a longer day, the trail continues beyond the Upper Falls toward the Ink Pots, a set of mineral-rich, emerald-green spring-fed pools seated in subalpine meadow—an entirely different ecosystem from the canyon below.

Practicalities matter. The standard route to the Upper Falls is roughly a 5–6 km round trip with about 120–180 m of elevation gain, mostly in the approach above the canyon. The boardwalks and metal stairs make the canyon accessible to a wide range of fitness levels, but the surface can be wet and icy: traction is non-negotiable in winter and advisable in shoulder seasons. Parking fills very early in peak summer; consider arriving at dawn, taking the seasonal shuttle from Banff when available, or using the Bow Valley Parkway pullouts and cycling in for quieter mornings. Banff National Park requires a valid park pass—purchase one online or at park gates—and be mindful that dogs must be leashed and are not permitted on the catwalks.

Safety is straightforward but important: keep to the boardwalk, watch for slippery planks and ice, and respect wildlife (elk and deer browse the meadow along the road; bears are present in the Bow Valley during warmer months). If you’re doing the Ink Pots extension, treat it like a full alpine day—layers, extra water, and a map or GPS. For winter canyon walks, microspikes are the minimum; join a guided ice-walk if you want an interpretive element or if conditions look unstable.

Where to go from here: many visitors couple Johnston Canyon with a loop drive along the Bow Valley Parkway for wildlife watching and viewpoints, or they continue to Lake Louise and Moraine Lake. In winter, some travelers use the canyon as a morning activity before heading to Mount Norquay or Sunshine Village for skiing.

Johnston Canyon is compact enough to be a day-staple and vivid enough to linger in memory. It’s not the remotest or quietest piece of alpine wilderness, but it is, in its way, a distilled mountain experience: the sound of water that insists on movement, the rock that resists and yields, the human-made catwalks that let you step closer without stepping over the line. If you go, plan for traction, arrive early, and let the canyon tell you its story in riffled water and frozen curtains—then move on, quietly, leaving no trace.
