The Grotto Canyon Icewalk allows you to walk directly on a frozen creek bed at the bottom of Grotto Canyon past unusual rock formations, ancient Native rock art, and icefalls. The Icewalk is 4.2km (2.6 miles) and has an elevation of 100 metres (328 feet), with a total walking time of 2 - 2.5 hours. This icewalk is generally considered easy, with a few small inclines.Johnston Canyon is one of the most popular attractions in Banff National Park, and has a network of steel catwalks built into the canyon walls that allows you to walk right along the frozen waterfalls (rather than directly on the ice). There are two Johnston Canyon Icewalk options, the daytime icewalk is a 4 hour tour that includes both the lower and upper falls with 2 - 2.5 hours of walking and is a little more strenuous due to the increased distance (5.4km) and elevation gain of 135 metres (443 feet). The evening icewalk is a 2.5 hour tour that visits the lower falls with 1.5 - 2 hours of walking 2.2 km with an elevation gain of 65 metres (213 feet) and includes a souvenir headlamp to light your way under the stars. On both Johnston Canyon Icewalks the walk is mainly up above the creek bed on a series of trails and catwalks.
