About Trail Creek Hot Springs
Trail Creek Hot Springs is tucked into a forested drainage near Yellow Pine, deep in Boise National Forest. Getting here takes rough Forest Service roads plus a 1.5-mile hike, which keeps crowds virtually nonexistent. Cascading rock-lined pools run 95-125F, with the upper pools hottest and lower pools cooled by creek water mixing in.
