Banff Upper Hot Springs vs Radium Hot Springs

Banff or Radium hot springs? Compare drive time, pool size, vibe, and price between the two Rocky Mountain mineral pools — and which one suits your trip.

Banff Upper Hot Springs vs Radium Hot Springs — comparing the two open-air mineral pools of the Canadian Rockies in Banff and Kootenay national parks

Two of the Canadian Rockies’ best-loved soaks sit a mountain range apart: the Banff Upper Hot Springs on Sulphur Mountain, and Radium Hot Springs in Kootenay National Park, British Columbia. The water in both is kept at the same comfortable 37–40°C — so the real difference isn’t the heat, it’s the day out. This guide sorts out which one fits your trip.

The Short Answer

If you’re based in Banff and want a quick, scenic soak, the Upper Hot Springs is unbeatable for convenience — it’s six minutes from town. If you want a bigger pool, more room to spread out, and a cool-down pool too — and you don’t mind a scenic drive over the Continental Divide — Radium is the more relaxed soak. Many people do Radium only when they’re already heading that way.

Banff Upper Hot Springs: Convenience & the View

The big draw is how easy it is: a short drive or a Roam-bus ride from downtown Banff, with sweeping views of Mount Rundle and the Bow Valley from Canada’s highest hot pool. The trade-off is size — there’s one pool, and at peak times (weekends, and roughly 3–5 PM) it fills up and the edge seating goes early. Go off-peak and it’s a genuinely lovely, fuss-free soak with the best mountain panorama of the two.

Radium Hot Springs: Space & the Canyon

Radium sits dramatically in Sinclair Canyon, where the highway squeezes between sheer red cliffs. The pools are bigger than Banff’s, and crucially there’s a separate cool pool to swim in alongside the hot one — better for families and for cooling off. The catch is the distance: about 1.5 to 2 hours from Banff, over the Continental Divide on Highway 93 (a gorgeous drive in its own right, often with bighorn sheep near the village). Few people drive there just for the pool — but if you’re road-tripping the Kootenay/Icefields loop, it’s a perfect stop.

How to Decide

  • Choose Banff if you’re staying in or near Banff, want a soak without a big drive, and care about the mountain view. Best paired with the gondola next door.
  • Choose Radium if you want more space and a cool-down pool, you’re travelling through Kootenay or BC anyway, or you’d enjoy the Sinclair Canyon drive as part of the day.
  • Do both if you’re touring the Rockies for several days — they’re different enough to be worth it.

If your plan is Banff-based, the simplest way to fit a soak into a packed sightseeing day is a guided tour that includes a hot-springs stop — and you can read what that combo day looks like before you book.
