Stretching a formidable 27 miles, Jasper's Skyline Trail is a challenge for all but the most seasoned hikers. The journey is worth undertaking—nearly two-thirds of the route is above the tree line, which means you'll enjoy stunning panoramic views as the rule rather than the exception. The path runs from Maligne Lake back to the town of Jasper at the foot of Signal Mountain, traversing the Maligne Range mountains in the middle. There's a short window during which you can enjoy this trail, typically from late July until mid-September. The classic trip includes two nights of camping at Snowbowl and Tekarra campgrounds, but if you're pressed for time, hike like the locals: Many Jasperites choose to start early and finish late, conquering the entire length in a single day.
