Johnston Canyon, Natural valley in Banff National Park, Canada

Johnston Canyon is a valley in Banff National Park, Alberta, cut into limestone to a depth of about 1,539 metres above sea level, with Mount Ishbel rising 2,908 metres about 4.6 km to the east. Steel walkways bolted to the canyon walls carry visitors past waterfalls and carved rock. The surrounding land is open grassland under a boreal climate averaging −3 °C.

Johnston Canyon lies at 1,539 metres in a valley in Alberta, about 3,000 km west of Ottawa. Mount Ishbel rises to 2,908 metres roughly 4.6 km east of the canyon. The local climate is boreal, averaging -3 °C, with July highs near 12 °C and December lows around -14 °C.

Johnston Canyon's frozen waterfalls make it a winter ice-climbing venue in Banff National Park. The climbing routes form where the canyon's falls ice over, and the canyon lies below Mount Ishbel, whose 2,908-metre summit rises about 4.6 km to the east. The canyon floor sits at roughly 1,539 metres above sea level.

Two main routes serve different interests: a shorter path to the lower waterfalls and a longer one extending further upstream. Both trails are well-marked, though wet conditions make surfaces slippery during damper months and proper footwear is essential.

Johnston Canyon sits at 1,539 m in a valley below Mount Ishbel, which rises to 2,908 m about 4.6 km to the east. The surrounding land is sparsely populated, fewer than two people per square kilometre, and covered in subalpine vegetation. The climate is boreal, averaging −3 °C, with July the mildest month at about 12 °C.
