Hart Mountain Hot Springs (Antelope Hot Springs)

Hart Mountain Hot Springs, also listed as Antelope Hot Springs, rises at the eastern base of Warner Peak inside Hart Mountain National Antelope Refuge in Lake County, Oregon. The U.S. Fish and Wildlife Service manages the refuge, which covers about 278,000 acres on a fault-block ridge above the Warner Valley. The spring sits inside Hot Springs Campground, and guides describe a stone wall around the main pool.

From Lakeview, the refuge's recommended route runs 15.6 miles east on Highway 140, 19.6 miles north on the Plush Cutoff to Plush, then 23 miles east on Hart Mountain Road to refuge headquarters. Hot Springs Road continues about 4 miles south of headquarters to the campground. The refuge has no entry fee and is open 24 hours a day, year-round. Camping at Hot Springs Campground is free and first come, first served, with a limit of 14 days in any 30-day period and a 24-foot maximum for trailers. Refuge rules prohibit altering the spring, using soap and building fires at this campground. The campground closes when road access becomes impassable, and the refuge map lists seasonal roads as open from June 15 to December 1. In 2026 the refuge reported construction at headquarters and along Hot Springs Road, with possible stops.

President Franklin D. Roosevelt established the refuge on December 20, 1936, and a Civilian Conservation Corps camp operated on Hart Mountain in the late 1930s. The Warner Peak Fire in August 2024 burned through Hot Springs and Post Meadows campgrounds, and the refuge later added a buck and rail fence around the spring area to support riparian recovery. Plush, 23 miles west of headquarters, is the nearest community, and Lakeview is the county seat.
