The Crypt Lake hike is one of the most unique hikes you'll ever encounter. In 2014 National Geographic rated this hike as one of the World's 20 Most Thrilling Trails! The hike features a 15 minute boat ride across Upper Waterton Lake to the trailhead at Crypt Landing. The trail passes close to 4 spectacular waterfalls. A highlight for many is the steel ladder and 60 foot tunnel through the mountain. After a short maneuver around a cliff (with cable for added security), hikers arrive at beautiful Crypt Lake.
