Tunnel Mountain's trailhead is located right in downtown Banff, so you'll probably be able to set out on this hike directly from your hotel! This relatively easy trek allows you to conquer your first peak in the Canadian Rockies by climbing just 300 meters (950 feet) over 2.2 kilometers (1.4 miles). The well-maintained path switchbacks gently through a forested area before reaching a rocky, open alpine slope. Gaining the rounded summit offers spectacular views of the north ridge of Mount Rundle, downtown Banff, and a panoramic stretch of the Bow Valley. The hike should take two to three hours up and back.
