Hart Mountain National Antelope Refuge is one of Oregon's most remote and rewarding destinations, a 278,000-acre expanse of high desert steppe and mountain terrain that exists primarily for wildlife. The western escarpment rises 3,000 feet from the Warner Valley floor, creating a dramatic approach that sets the tone for what lies above. Free hot springs at the campground, vast pronghorn herds, and some of the darkest night skies in Oregon make this a bucket-list destination for overlanders who value solitude and natural beauty.
Fun Facts
Hart Mountain Antelope Refuge was established in 1936 specifically to protect pronghorn habitat.
The hot springs at the campground are free, primitive, and flow year-round at 104°F.
Pronghorn can reach speeds of 55 mph, making them the second-fastest land animal on Earth.
The refuge covers 278,000 acres, larger than many national parks.
