Banff Upper Hot Springs

Banff Upper Hot Springs is a developed outdoor mineral pool and heritage bathhouse on Sulphur Mountain, 1,585 metres above sea level. The water is kept at 37–40°C, with Mount Rundle and Cascade Mountain filling the skyline. Come for the open-air soak and the view; this is one heated pool, not a cave or a wild spring. Give it an hour or two if you want time to soak and look around.

Roam Route 1 is the easiest way to reach the springs from downtown Banff. Entry is first come at reception, with no advance bookings; weekends, school breaks and statutory holidays tend to mean longer waits. A park pass is required. The main parking lot sits at the foot of the hill, about 200 metres from the bathhouse by paved sidewalk, while three accessible stalls are beside the building.

There are lockers, changing rooms, showers and public washrooms. The pool has shallower and deeper areas, and the hot water can feel intense after a while; take regular breaks and drink water. Plan on one or two hours for a relaxed soak and a look around. Accessible changing rooms are at pool level, and an aquatic wheelchair is available on request; personal wheelchairs can't go into the spring water.

Indigenous Peoples used these sacred waters for healing and health before the 1880s. In 1883, Canadian Pacific Railway workers discovered the separate Cave and Basin springs, a discovery that helped lead to Canada's first national park. Europeans first visited Upper Hot Springs in 1884, so keep the two sites straight: this pool is farther up Sulphur Mountain, above the town.

The water begins as precipitation on Mount Rundle's high western slopes. It sinks into sedimentary rock, warms and picks up minerals deep underground, then rises along the Sulphur Mountain Thrust Fault after travelling more than three kilometres through the earth. That trip takes hundreds of years, which gives a soak here a much longer backstory than the pool itself.

The first bathing buildings were a log shack and the Grand View Villa, built in 1886. Fires in 1901 and 1931 destroyed earlier structures; the present federal heritage bathhouse opened on July 1, 1932, then was restored to its 1932 appearance in 1995–96. The historic building is part of the appeal, even though the visit itself is a straightforward outdoor-pool soak.

On a clear day, Mount Rundle and Cascade Mountain rise behind the pool and patio. For the classic photo, keep a strip of water in the foreground with the peaks above it; a mountain-only frame loses the reason this view belongs to the hot springs.
