About these waters
Also called Antelope Hot Springs, this is a single warm pool inside the Hot Springs Campground at Hart Mountain National Antelope Refuge, about twelve miles northeast of Plush. The 104-degree water sits in a semi-improved rock pool big enough for a handful of soakers, with free camping, restrooms, and some of Oregon's darkest night skies. Refuge roads are gravel and weather-dependent, so check conditions before the long drive in.

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.

Hart Mountain Hot Springs: FAQs
Do I need a reservation or permit to visit Hart Mountain Hot Springs?
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 Hart Mountain Hot Springs?
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 Hart Mountain Hot Springs?
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.
