Sheep Creek Hot Spring
Sheep Creek Hot Spring reaches 136 degrees Fahrenheit at 6,590 feet in the Payette National Forest, requiring a 3.6-mile hike through genuine backcountry near McCall. The spring runs nearly 98 degrees above the local average air temperature of 38 degrees, one of the largest thermal differentials among Idaho's wilderness springs.
The trail climbs through subalpine forest in Valley County, where annual snowfall averages 163 inches and the landscape stays white well into summer. At the spring, hot water flows through a rocky clearing surrounded by conifers and high-elevation meadow. The air is thin and cold at this altitude, and steam hangs visibly over the source. The Frank Church-River of No Return Wilderness lies nearby, adding to the area's undeveloped character.
This spring emerges along fault structures in the Idaho Batholith, where deeply circulating groundwater absorbs heat from cooling granitic rock. The Payette National Forest has administered this land since 1908, and the spring's difficult access has kept it free from development. The nearest historic structure is the Johnson Creek Guard Station, built in 1922 and still available as a rental cabin.
Plan for a full-day outing given the 3.6-mile hike each way and the elevation. Snow typically blocks access until late June or July. The source water is far too hot for direct contact — look for downstream pools where it cools to soaking temperature. Johnson Creek Guard Station, 13.6 km away, can be reserved for overnight stays.
