Jerry Johnson Hot Springs

## Overview Jerry Johnson Hot Springs is a beloved series of natural hot spring pools nestled along the Lochsa River corridor in the Clearwater National Forest of central Idaho. Located near milepost 152 on U.S. Highway 12, these free, primitive hot springs sit at an elevation of roughly 3,100 feet in a lush, forested canyon setting. The springs have long been a popular soaking destination for travelers along the Lewis and Clark Historic Trail, offering a rare chance to relax in naturally heated mineral water surrounded by old-growth cedar and fir trees. The hot springs consist of several pools of varying temperatures, fed by geothermal water that emerges from the earth at temperatures that can exceed 110°F (43°C) before cooling as it flows into the lower pools. Visitors have historically reported that the upper pools tend to be hotter, while the lower pools closer to Warm Springs Creek offer a more moderate, comfortable soak. The springs are undeveloped and clothing-optional, maintaining a rustic, backcountry feel. Jerry Johnson Hot Springs are situated within the traditional homelands of the Nez Perce (Nimiipuu) people, who have inhabited the Lochsa River region for thousands of years. The area gained further historical significance as part of the route traveled by the Lewis and Clark Expedition in 1805, and the nearby Lolo Trail remains one of the most storied passages in American frontier history. ## Directions 1. From Missoula, Montana, head west on Interstate 90 and then take U.S. Highway 12 West toward Lolo and Kooskia, Idaho. 2. Continue on Highway 12 along the Lochsa River for approximately 90 miles past Lolo Pass. 3. Look for the Warm Springs Pack Bridge trailhead and parking area near milepost 152 on the south side of Highway 12. 4. From the parking area, cross the footbridge over the Lochsa River and follow the well-worn trail along Warm Springs Creek. 5. The hike to the hot spring pools is approximately 1 mile (roughly 20–30 minutes) along a mostly flat, forested trail. 6. The first pools you encounter will be the lower, cooler pools. Continue upstream for hotter soaking temperatures. **GPS Coordinates:** 46.4629, -114.8733 ## What to Expect The trail to Jerry Johnson Hot Springs is relatively easy and mostly flat, following Warm Springs Creek through a beautiful old-growth forest. The path can be muddy and slippery in wet conditions, and creek crossings may be necessary depending on the season and water levels. At the springs, you'll find a series of hand-dug and naturally formed soaking pools along the creek. Water temperatures vary by pool — the upper pools nearest the source tend to be the hottest, while lower pools mix with cool creek water for a more temperate soak. The pools are entirely primitive with no facilities, restrooms, or trash receptacles, so visitors should plan to pack out everything they bring in. The springs are accessible year-round, though winter visits require caution due to snow-covered trails and icy conditions. Summer and early fall are the most popular times, and the pools can get crowded on weekends. Early morning or weekday visits offer a more peaceful experience. Be aware that the area is bear country — both black bears and grizzly bears are present in the Clearwater National Forest. The springs are clothing-optional by longstanding local custom. There is no fee to visit, and no permit is required. Camping is available at nearby Forest Service campgrounds along Highway 12, including Wendover and Whitehouse campgrounds.
