The Tunnel Mountain Trail in Banff offers a relatively easy to moderate hike with stunning views of the Canadian Rockies. The 4.3 km trail with 400m elevation gain, starts near the town of Banff, provides a good workout with its steep incline but rewards hikers with panoramic vistas of the Bow River and surrounding area. With a mix of switchbacks and level sections, this popular trail is accessible to hikers of all ages and abilities. Don't forget to pack water, snacks, and your camera for this picturesque adventure in the heart of Banff National Park! We did this for sunrise and it was super pretty. You can do it in winter or summer, just bring crampons in winter. Tunnel Mountain Summit Trail | Banff & Lake Louise Tourism
