Headquartered in the town of Canmore, a little more than an hour’s drive west of Calgary, Canmore Caverns conducts guided cave tours. Excursions of various lengths include an alpine hike up Grotto Mountain, so called for the spring-fed underground grotto you’ll visit in Rat’s Nest Cave. The cave’s eponymous critters, bushy tailed wood rats, are cute as Pikachu.
