Cave and Basin National Historic Site sits at 311 Cave Ave in Banff, around the natural hot springs whose discovery led to the creation of Canada’s first national park in 1885. Walk through the tunnel to the original cave and its warm mineral water, then explore interactive exhibits on the springs, local wildlife and the history of national parks. Boardwalks and trails lead through marshland and nearby woods. The springs are protected, so bathing is not allowed; come to see the site and learn about its natural and cultural history.
The springs and the start of Banff National Park
The Cave and Basin site marks the beginning of Canada’s national parks system. In 1883, three railway workers found the hot springs in a cave at the base of Sulphur Mountain. Their discovery led to disputes over ownership, and in 1885 the area around the springs was protected as Canada’s first national park, then called the Rocky Mountains Park of Canada.
The springs were known to Indigenous peoples long before the railway workers arrived. The site lies within the traditional territories of many Indigenous Nations, including Îyârhe Nakoda, Siksika, Kainai, Piikani, Tsuut’ina, Ktunaxa, Secwépemc and Métis. The hot springs have cultural significance, and the pools are no longer open for bathing.
Inside the cave and interpretive centre
A tunnel leads into the original cave, where naturally warm mineral water flows through the rock. Look for the mineral deposits along the walls and the signs inside the cave as you make your way toward the pool. Outside, an emerald-coloured basin also holds warm spring water.
Interactive exhibits explain how the thermal springs formed, the history of Banff and the development of Canada’s parks. A four-screen visual presentation introduces the country’s network of protected places. Displays also cover local wildlife and conservation, including the rare hot spring snail found in the area. The springs are protected for conservation, so the visit is for viewing and learning, not swimming.
Tours, trails and seasonal activities
You can explore the site independently or join a guided tour. Options described for the site include a short introduction to its main points and a longer natural history tour. Cave tours take visitors through the underground passages; Saturday night lantern tours explore the cave by lantern light. Check the Parks Canada website for current tour details before planning around a specific tour.
Outside the buildings, boardwalks cross marshland and connect with walking routes through the nearby woods. The Marsh Loop is one option, and trails around the site vary in length. Interpretive panels along the way explain local geology, plants, wildlife and history. In winter, seasonal activities have included mini curling, box hockey and displays of vintage Banff Winter Carnival films and photographs.
Planning your visit
The historic site is at 311 Cave Ave in Banff. Roam Transit’s Yellow route 4 is one public transport option noted for getting there. An annual park pass provides free admission. If you are buying admission, avoid third-party vendors, which may not provide access to every area of the site.
Set aside time for both the cave and the outdoor paths if you want more than a quick look. The warm pools cannot be used for bathing; Banff Upper Hot Springs is a separate place to go for a soak. Choosing an off-peak time can make the visit quieter.
