In the winters of Banff National Park, sub-zero temperatures turn mighty waterfalls into glittering pillars of ice. Suspended in time, these frozen falls look almost otherworldly. You can experience two locations for ice walk tours. The most popular would certainly be Johnston Canyon which has a network of steel catwalks built into the canyon walls that allows you to walk right along this cathedral of ice. Add a touch of extra drama to your experience and head back after dark on a nighttime tour of Johnston Canyon where your headlamp illuminates the way. Grotto Canyon is the other location on the outskirts of Canmore. With less crowds, you will be lead along a frozen creek bed through a narrow canyon to see ancient native pictographs. Each ice walk offers an experience that is truly unique to Banff. This tour is recognised as a Canadian Signature Experience – a collection of once-in-a-lifetime travel experiences found only in Canada.
