Hart Mountain Hot Springs or Antelope Hot Springs are a collection of hot springs nestled perfectly within the confines of the Hart Mountain National Antelope Refuge. Bordered by rock walls, the main soaking pool is 8 by 11 feet in diameter and 4-foot deep. Another smaller undeveloped pool is located 100 yards away.

Hart Mountain Hot Springs was created by a rancher who stuck a stick of dynamite into a rock with bubbling water spouting out.

Hart Mountain National Antelope Refuge was established in 1936. This mountainous area is a perfect location for camping in the warmer months of the spring, summer, and fall. You should 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, wildlife observation. The refuge, in its entirety, is breathtakingly scenic and is the ideal location for long enjoyable hikes.


The main hot spring is surrounded by rustic stone walls protecting those within from the chills of the cold winds. Hot mineral water emerges from fissures in the concrete bottom at a temperature of about 100°F.

The small hot spring pool with a splendid unimpeded view of the mountain ranges is ideal during warmer weather. The pool’s gravel and bedrock bottom provide the base for spring water to bubble up from at a temperature up to 104°F. If you go along the channel, you will find more smaller hot spring pools.

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 during storms, drifting snow, muddy conditions, or landslides.

  1. We were wondering what the road conditions were like up to the campgrounds as well as the distances to the hot springs from each? Is pulling a small trailer doable, or do the roads rattle it too much? Thanks!
