About these waters

A free, primitive soak on BLM land about ten miles northwest of Anaconda, reached by a short walk from a gravel pullout off Warm Springs Creek Road. Visitors have stacked rock dams into several pools running 95–104°F, the largest roughly fifteen feet across. There are no facilities at all — no toilets, no trash cans, no cell service. Clothing-optional by local custom; best visited spring through fall, with winter access requiring skis or snowshoes.

Good to know

  • Listing researched October 2026 — prices and hours change, always confirm with the spring before visiting.
  • Hydrate between soaks and limit hot soaks to 15–20 minutes — mineral water dehydrates fast.
  • Wild springs run on the honor system: pack out everything, leave the pool cleaner than you found it.

Gigantic Warm Spring: FAQs

Do I need a reservation or permit to visit Gigantic Warm Spring?

No reservations — wild springs are first-come, first-served. Some trailheads require a parking pass or day-use fee, so check the listing details and current land-manager rules before you go.

What should I bring to Gigantic Warm Spring?

Swimwear and a towel, drinking water, a trash bag (pack out everything, including food scraps), and a headlamp if you're staying for sunset. Never bring glass near a wild spring — broken glass in a pool ruins it for everyone.

Is the water temperature reliable at Gigantic Warm Spring?

Wild spring temperatures shift with seasons, rainfall, and river levels — a pool that's perfect in October can be scalding or flooded in May. Test the water with a hand before getting in, and check recent trip reports for current conditions.
