Crypt Lake Trail of 8.7 kilometers one way is easily one of the best hiking trails in Canada. Letting you explore the woods of Waterton Lakes National Park, this trail poses some challenges even for experienced hikers. Though some part of the trail easy with an open walk through the valley, the last part here is where you have to ascent to Crypt Lake. But reaching the pretty alpine Crypt Lake is worth all the efforts as tranquil beauty here will soothe your mind. Keep in mind that animals like bear, deer, and mountain goat are often sighted around here.
