Due to severe fires in the early to mid-1900s, several fire lookouts were built in the Rockies, and the Paget Fire Lookout is the oldest in Canada's national parks. This 7-km (4.3-mile) moderately difficult round-trip hike, with 520 meters (1,706 feet) of elevation gain, will have you switchbacking through the forest until you almost reach the lookout shelter (which is no longer in use). Allow plenty of time to take in the amazing views of the Kicking Horse River valley, the Continental Divide, and the surrounding peaks from the strategically placed bench. If you're feeling energetic, you can continue on to Paget Peak, but beware that it's steep, with a 446-meter (1,463-foot) elevation gain on the 1.4-km (0.8-mile) trail. The trail is also challenging because of several scree-filled and exposed sections, and there can be snow at the summit well into July. If you're a seasoned hiker, however, the views from the top are worth it. Difficult.
