Tackle Rat’s Nest Cave, located near Canmore, Alberta, on this all-day adventure tour. After being outfitted with your gear, head out on a roughly 30-minute hike up to the cave. Along the way, learn how caves are formed and the geologic history of the area, plus possibly spot bighorn sheep. Once at the cave, you’ll rappel down 59 feet (18 meters) and begin navigating the route, which includes some challenging sections that involve climbing, crawling, squeezing, and sliding through the cave. At the end, reach the grotto with its crystal-clear pool and stalactites and stalagmites.
