Lava Hot Springs, Natural hot springs in Lava Hot Springs, Idaho, USA

Lava Hot Springs is a geothermal facility with multiple outdoor pools containing mineral-rich water that maintains consistent warm temperatures year-round. The site has separate areas for soaking in the therapeutic springs and for recreational swimming.

The springs were used by Bannock and Shoshone peoples before European contact. In 1890, English immigrants John and Mary Hall homesteaded the site, and in 1902 the Shoshone and Bannock ceded the springs and surrounding land to the U.S. government.

The mineral waters draw people seeking therapeutic benefits from the warm springs. This place has served as a gathering spot for generations where visitors spend time with family and friends in a relaxed setting.

The location is about two hours north of Salt Lake City and is reasonably easy to reach by car. Visitors should bring appropriate swimwear and prepare for varying weather conditions, especially if visiting during cooler months.

The springs' vents run through Paleozoic quartzite and younger travertine, and the water leaves the ground at 113°F (45°C) with a flow of 34 gallons (130 liters) per second. Its mineral load includes manganese, sodium, iron, calcium bicarbonate, potassium, magnesium, zinc and fluoride.
