Cave and Basin National Historic Site is Located just a short walk or drive from downtown Banff. This site marks where, in 1883, three railway workers discovered thermal hot springs inside a hidden cave. Their find led to the creation of Canada’s first national park, and eventually, the entire national parks system. But the story goes back further than that even. Indigenous Peoples have known and cherished this place for over 10,000 years, using the warm waters for healing and ceremony.

You can explore the original cave via a short tunnel that leads to a turquoise pool — the same one that sparked the creation of Banff National Park. Outside, boardwalks offer a peaceful walk with mountain views and signs. Inside the visitor center, you’ll find interactive displays, short films, and exhibits that cover everything from geology and wildlife to the internment of Ukrainian Canadians during World War I.

While you can no longer swim here, the site still offers a rich and immersive experience. Plan to spend 1–2 hours exploring the cave, museum, and boardwalks. If you’re up for more, the nearby Marsh Loop and Sundance Trail offer easy hikes with great views.
