Hart Mountain Hot Springs or Antelope Hot Springs are a collection of springs nestled perfectly within the confines of the Hart Mountain National Antelope Refuge. The main 7 by 10 feet soaking pool, bordered by rock walls, is 4-foot deep. Another smaller undeveloped pool is located 100 yards away.
A rancher is said to have stuck a stick of dynamite into a rock with bubbling water spouting out of it, thus leading to the creation of the Hart Mountain Hot Springs.
Established in 1936, Hart Mountain National Antelope Refuge is the perfect location for camping in the warmer months of the spring, summer, and the fall. Be well prepared because sometimes high desert conditions can be extreme. Due to a higher altitude, nighttime temperatures can go below the freezing point at any time of the year. During the hot summer months stay hydrated, use sunscreen and insect repellent.
This destination features a multitude of excellent spots for hunting, fishing, rock hounding and of course wildlife observation. The refuge, in its entirety, is breathtakingly scenic and is the ideal location for long enjoyable hikes.
For all those desiring a stunning camping location, the camping spots at Hart Mountain are made additionally spectacular by the abundance of cool springs and crackling creeks. Furthermore, accessible all year round, the main hot spring is surrounded by rustic stone walls protecting those within from the chills of the cold winds.
The developed spring is quite deep and for those not wanting to be engulfed by the water, the undeveloped springs are ideal. With a splendid unimpeded view of the mountain ranges, these springs are the absolute top notch. The pool’s gravel and bedrock bottom provide the base for lovely spring water to bubble up from.
The Hart Mountain, Frenchglen, Blue Sky, and Hot Springs Roads are open and maintained year-round. Any vehicles can be used. Other National Refuge's roads are not maintained. Four-wheel drive vehicles with high clearance are recommended. Any road can become hazardous due to storms, drifting snow, muddy conditions, or landslides. Check current road conditions on the U.S. Fish & Wildlife Service website.
