When you visit Banff National Park, a Tunnel Mountain hike is one of the best ways to enjoy panoramic views without a strenuous trek.

In this detailed guide, you’ll discover everything you need to plan and enjoy a Tunnel Mountain hike — including trail facts, the best times to go, what to bring, safety tips, and nearby attractions.
Where is Tunnel Mountain?
Tunnel Mountain sits just above the town of Banff in Banff National Park, Alberta. Despite its name, no tunnel runs through the mountain — the name comes from an abandoned 19th-century railway plan.
Trailhead location:
- The main trailhead is near Banff Centre on St. Julien Road — a short 10-15 minute walk from Banff Avenue.
- Another access point is from Tunnel Mountain Drive (limited parking).
Tunnel Mountain is sometimes called Sleeping Buffalo by Indigenous peoples, reflecting its shape and cultural significance.
