Sulphur Mountain Trail

Sulphur Mountain Trail is a steady out-and-back climb from the Banff Upper Hot Springs parking area to the top of the Banff Gondola on Sulphur Mountain. The stored line follows the physical one-way corridor once, about 4.8 km (3.0 miles) each way; plan on about 6.0 miles (9.6 km) total on foot and roughly 4 hours round trip. The route climbs through forest on a long series of switchbacks, with the grade becoming more noticeable on the upper slopes.

At the top of the gondola, the route connects with the summit complex and the boardwalk toward Sanson Peak and the Cosmic Ray Station. The final 0.5 km to Sanson Peak is an optional continuation beyond the top-of-gondola endpoint represented by this trail line. Views open across the Bow Valley and surrounding ranges as you gain elevation, while the summit facilities can be busy because visitors also arrive by gondola.

The trail is a maintained mountain path with firm soil, short paved or decked sections near the trailhead and summit, and sustained climbing. Parks Canada rates it moderate; the distance and 655 m of gain still make it a substantial hike. Snow and ice can persist in shoulder seasons and winter, and mountain weather can change quickly.

Park at the Banff Upper Hot Springs parking area at the end of Mountain Avenue and follow the signed access to the trail. Parking is limited and fills quickly; Roam Route 1 serves the area. A valid Parks Canada pass is required. Dogs must remain on leash and under physical control. Carry water, food, layers, traction when conditions are icy, navigation, and bear spray. Check current trail conditions, closures, and weather before departure.
