2. Crypt Lake
Another hike featured in National Geographic, Crypt Lake was named one of the world’s most thrilling trails in 2014. Hikers must take a 15-minute ferry across Upper Waterton Lake to begin the trail, but you’ll pass four spectacular waterfalls, go up a steel ladder and through a tunnel to get to Crypt Lake. The day hike gives visitors a chance to explore one of Alberta’s best-kept secrets and a UNESCO World Heritage Site: Waterton Lakes National Park. Just don’t miss the boat home!
