About Coyote Hot Spring
Coyote Hot Spring, also known as Prince Albert Hot Springs, Idaho is a free primitive geothermal spring on BLM land in the Bennett Mountain Hills of Elmore County, above the small town of Glenns Ferry and the Snake River Valley. The source water emerges from the hillside at approximately 130 degrees Fahrenheit. By the time it reaches the soaking pools, it cools to a comfortable 100 to 104 degrees. Mountain Home, on Interstate 84, is the nearest city with full services.
The upper pool is built from stone and cement, cleverly damming the spring flow to create a soaking area that comfortably fits up to five people. Smaller stone-lined pools farther down the hill accommodate two to four people each. Locals have installed PVC pipes that allow pools to be drained and refilled with fresh hot water from the source. The spring has a slight sulfur smell. The USGS coordinates for Coyote Hot Spring match those in the GNIS database for Prince Albert Hot Springs. Both names refer to the same feature.
The setting on the Bennett Mountain hillside offers panoramic views across the Snake River Valley, making this one of the more scenic free hot springs Idaho offers in the southern mountains.
