Goldbug Hot Springs - Free soaking · donation encouraged in Salmon, ID (2026)
A two-mile climb up BLM Trail #642 leads to cliffside tubs with sweeping views of the Salmon River Mountains. Backpackers spread out across primitive campsites tucked between the cascades and the main overlook pool.
Goldbug Hot Springs is a six-tier cliffside soak above the Salmon River in Idaho's Lemhi County — reached via a steep, exposed 2-mile climb up BLM Trail #642, with 1,300 feet of elevation gain. Six terraced rock-walled pools step down a cliff face, each fed from a single 130°F source vent, with the temperature dropping as you descend the terraces. The trail is a serious effort (not a casual walk), the views from the top tier sweep across the Salmon River Mountains, and the dispersed camping along the trail is some of the best primitive camping in central Idaho. Free, BLM-managed, very busy on summer weekends despite the climb.
What to expect
Park at the trailhead off Highway 93 about 24 miles south of Salmon. Hike 2 miles up — switchbacks, exposed rock, no shade for most of the climb. Allow 60-90 minutes up. Six pools at the top, each holding 4-8 people; the upper-most are hottest (~110°F, near the source) and the lower terraces cool progressively. Backpackers spread out across primitive sites along the trail. Pack out everything; no facilities at all.
