Jerry Johnson Hot Springs: A Pristine Soaking Spot in Idaho's Wilderness

Jerry Johnson Hot Springs is a popular day-use destination nestled in the Clearwater National Forest of southeastern Idaho, near the Montana border. The springs are situated along the east bank of Warm Springs Creek, providing a serene natural setting for soaking.

Due to its year-round popularity, the Forest Service has implemented a nighttime closure. The hot springs are open from 6 am to 8 pm daily.

To reach Jerry Johnson Hot Springs, park at the Warm Springs Park bridge trailhead, located 0.5 miles west of mile marker 152 on US 12. A large parking area with a vault restroom is available on the northern side of the road.

From the parking area, cross the bridge and follow the Warm Springs Creek Trail (Trail 49) for a scenic 1.4-mile hike up the valley to the springs. The trail is easy with a gradual incline and offers stunning mountainous views.

Jerry Johnson Hot Springs - Geothermal Water & Soaking

The hot springs has three distinct sources, each feeding a series of soaking pools:

The first "waterfall pool" is located right at the waterline in late summer with a temperature of around 105°F (41°C).

Farther from the river, there is a group of pools of various sizes. The largest pool with a big rock has a temperature of around 98°F (37°C).

Additional pools are located along the river's bank. The pool furthest from the river and closest to the trail is the hottest, fed directly by springs emerging at 110°F (43°C). The temperature of the other bank pools is generally lower as they are mixed with cooler river water.

During different times of the year, visitors may create new pools, though these might not survive the winter runoff.

Clothing is optional at Jerry Johnson Hot Springs, but swimwear is common, especially given the mixed crowd of visitors.
