About this spring
Two natural hot spring pools at the eastern base of Warner Peak inside Hart Mountain National Antelope Refuge: a developed stone-walled pool (~9x12 ft) and a smaller primitive pool ~100 yards away. The adjacent free Hot Springs Campground has primitive sites. Extremely remote high-desert refuge managed for pronghorn and bighorn habitat. Extremely remote: no cell service, no water, 2+ hrs from services. Check FWS Current Conditions — refuge partially closed by wildfires in recent years.
Hart Mountain Hot Springs is a pair of soaking pools at the Hart Mountain National Antelope Refuge headquarters in Lake County, Oregon. A developed 4-by-8-foot concrete pool with a covered deck sits beside the refuge's campground; water is piped in from a spring on the hillside and maintained around 95-100°F. A second, more primitive stone-and-gravel pool sits a short walk away on a hillside, with cooler water and more solitude. The refuge manages both pools as free amenities for campers and day visitors; they're popular in spring and fall when birdwatchers come to see sandhill cranes, sage grouse, and pronghorn. The springs are part of the same geothermal system that feeds Antelope Hot Springs (listed separately) a few miles away, but they're closer to the refuge's developed facilities and easier to reach.
Directions & trailhead access
From Plush (~28 mi by road), take Hart Mountain Rd then Hot Springs Rd north into the refuge to Hot Springs Campground; pools are in the campground. Roughly 67 miles northeast of Lakeview — unpaved roads, high clearance recommended.
Oregon geothermal context
Oregon splits cleanly in two: Cascade volcanic springs like the Umpqua corridor pools west of the crest, and high-desert basin springs like the Alvord area east of it. Western sites sit in dense wet forest prone to fire closures and winter road washouts; eastern ones are remote sagebrush tubs under enormous skies. Both ends reward checking land-manager alerts before driving out.
What a primitive site means here
Primitive springs have no facilities: no changing rooms, no trash service, often no maintained road to the pool. Expect natural rock or gravel bottoms, water temperature that varies by spot and season, and other visitors who may treat the site informally. Pack out everything you bring, test the water before entering, and leave the pool cleaner than you found it.
Best time to visit
June – September (Late Spring through Early Autumn)High-altitude mountain access routes and backcountry trailheads can experience seasonal snowpack from November through May. Peak summer and early autumn provide clear trail access and pleasant evening soak conditions.
