About Bear Creek Hot Spring
Bear Creek Hot Spring, Idaho is a secluded backcountry hot spring in the Caribou-Targhee National Forest near Swan Valley in Teton County, eastern Idaho. The spring feeds a natural pool approximately 10 by 20 feet at a comfortable soaking temperature, set in a forested canyon along Bear Creek near the Palisades Reservoir. Swan Valley, a small community on US Highway 26 between Idaho Falls and Jackson Hole, is the nearest settlement.
The spring sits in the North Caribou Highlands at approximately 6,900 feet elevation, in a landscape of lodgepole pine, aspen groves, and mountain meadows. The secluded location, reached only by a challenging 13.7-mile hike, means the spring sees relatively few visitors compared to more accessible Idaho hot springs. The area is popular with hikers, birders, and hunters (during archery season). Bear Creek Hot Spring is one of several natural hot springs in Idaho near the Palisades Reservoir and the Snake River corridor.
The pool is a natural feature on public National Forest land. Conditions vary with season and use.
Location & Access
Getting to Bear Creek Hot Spring
Bear Creek Hot Spring is reached by a challenging 13.7-mile out-and-back hike from the Bear Creek trailhead on the Palisades Reservoir side, with approximately 1,781 feet of elevation gain. The hike takes 5.5 to 6.5 hours to complete and is rated as hard, with steep sections concentrated near the end of the trail.
From the Bear Creek trailhead, hike up Bear Creek canyon on narrow singletrack through lodgepole and aspen forest, then climb onto sun-exposed benches above the canyon. About one mile up Warm Springs Trail 148, a faint spur drops southeast to the pools. The spur is not well marked, so pay close attention. Creek fords along the route can run knee-deep during spring runoff.
Directions to the Trailhead
From Swan Valley, drive south along the Palisades Reservoir on US Highway 26 to the Bear Creek trailhead area near Irwin. The trailhead is at coordinates 43.269, -111.304. For visitors seeking hot springs near Swan Valley, Bear Creek is the most secluded backcountry option. Palisades Hot Springs (a lakeshore seep at the reservoir) and Heise Hot Springs (a developed resort near Rexburg) are more accessible alternatives in the eastern Idaho region near Jackson Hole.
Suitability & Accessibility
Who Should Visit Bear Creek Hot Spring
Bear Creek Hot Spring suits experienced hikers seeking a secluded, uncrowded backcountry hot spring soak in the Idaho mountains. The 13.7-mile round trip with 1,781 feet of elevation gain is a full-day effort that filters out casual visitors, resulting in a quiet, often private soaking experience. The pool is large enough for several people at a comfortable soaking temperature.
The trail is best hiked from March through October. Dogs are welcome and may be off-leash in some areas. The area near the pool is used as a hunting camp during archery season, so expect more company in early fall. Due to the secluded nature of the spring, clothing-optional soaking is common. Open spaces around the springs provide room for setting up camp if planning an overnight trip.
Accessibility at Bear Creek Hot Spring
The spring is not wheelchair accessible. The challenging 13.7-mile backcountry trail is suitable only for fit hikers. No facilities exist at the spring. Those exploring natural hot springs Idaho offers near Swan Valley who prefer easier access should visit Heise Hot Springs (a developed resort with pools) or Palisades Hot Springs (a lakeshore seep accessible by a short walk along the reservoir shoreline, requiring no backcountry gear or extended hiking whatsoever).
Safety & Etiquette
Bear Creek Hot Spring Safety Tips
Bear Creek Hot Spring is in remote backcountry in the Caribou-Targhee National Forest, and visitors should be fully prepared for a challenging day hike or overnight trip. Always test water temperature before entering. Bring adequate water, food, and navigation tools for the 13.7-mile round trip.
Creek fords along the Bear Creek Trail can be hazardous during spring runoff, with knee-deep swift water and undercut banks. Use caution at all crossings. The trail has off-camber sidehills, roots, and gravel on hardpan that can be slippery when wet or muddy. The steep sections near the end of the trail require steady footing.
Wildlife and Seasonal Awareness
Black bears and moose are present in the Caribou-Targhee National Forest. Make noise on the trail to avoid surprising wildlife. Store food properly. Ticks are a concern, especially in spring and early summer. Check for ticks after your hike. During archery season, hunters may be camping near the springs. Wear visible colors if hiking during hunting seasons.
Leave No Trace
The springs sit in fragile riparian ground. Stay on established paths and pack out all trash. Do not alter the pool or surrounding area. Inform someone of your hiking plans before departing, as cell service is not available on the trail. The nearest medical facilities are in Swan Valley or Idaho Falls, both a significant drive from the trailhead. Carry a first aid kit and a satellite communication device for emergencies in this remote area.
