Bonneville Hot Springs

• Bonneville Hot Springs is a scalding-temperature geothermal site
• There are a few soaking pools at the river edge

Bonneville Hot Springs sits in the beautiful Boise National Forest at the Warm Springs Creek, 20 miles northeast of Lowman. This serene place features beautiful Idaho nature views, hot spring waterfalls, scalding mineral streams, and a fun soaking experience.

A 0.4-mile trail starts from the parking area near the campground and leads along the creek through the forest of towering Ponderosa pine and Douglas fir to the geothermal field. At the end of your hike, you will see hot water oozing out of the ground, creating multiple streams and puddles. Those might be scalding hot, so be careful when you walk.

Geothermal Water & Soaking

Geothermal mineral water comes from multiple springs emerging from the ground at temperatures up to 180° F (82° C). Water flows from the hill creating scalding creeks that follows its way to the Warm Springs Creek. It creates scalding waterfalls that cascade from the bank bluff. The sulfur odor is very present.

When heading down to the creek and pools, you likely will cross the hot stream separating the pools. Take caution crossing it. Though the river water is coming here, some areas might be extremely hot and even scalding.

Rock-and-sand pools lining the creek is great place to soak. Hot water coming from the hill is mixed with the river water that allows finding comfortable temperature for you. Water temperature varies greatly, so always check it and add river water if needed.

Other opportunities to bathe are the old wooden "soak shack" bathhouse with an antiquated cast iron bathtub. Water in a bathtub is around 104°F (40°C). You need to drain the tub after each use.

Please remember that nude soaking and soap at the springs are prohibited in the Lowman Ranger District of the Boise National Forest. No pets or glass containers are allowed at or near the spring.
