About Gregson Hot Springs

Gregson Hot Springs is a natural hot spring in Montana.

At that temperature it's temperature unrecorded — check current conditions and always test the water before getting in.

Plungeworthy rates Gregson Hot Springs 5.4/10 — if you're passing. The score weighs its scale, how confidently it's mapped, and its character.

What you'll find

Hours: Guest pool hours 7am–10pm

Warnings: Don't drive in expecting a day soak.

Where it is

Before you go

The pin marks the feature, not a trailhead or a legal route in. Some sit on private land or need a real hike, and conditions change with season and rain. Check local access, don't trespass, and never enter water — hot or cold — where it isn't safe.
