Teapot Hot Spring
Teapot Hot Spring reaches 142°F with a strongly alkaline pH of 9.3, making it one of the hotter sodium-dominant springs in central Idaho. Located on federal land within Payette National Forest at 3,900 feet elevation, it sits just 40 meters from South Fork Salmon River Road, providing direct roadside access on public land.
The spring emerges in a forested mountain corridor along the South Fork of the Salmon River in Valley County. At 3,900 feet, the surrounding landscape is dense conifer forest typical of the Payette National Forest, with the river canyon cutting through steep, timbered slopes. The area receives 151 inches of snow annually and averages 46.8°F year-round, creating a cold-climate mountain environment where thermal water stands out sharply against the landscape.
The spring takes its name from its appearance or discharge pattern, though specific historical documentation is limited. It lies within the broader South Fork Salmon River corridor, a drainage historically used by Shoshone-Bannock peoples and later by miners and trappers in the 19th century. The Forest Service currently manages the site as open-access within Payette National Forest.
Summer through early fall provides the most reliable access, as the area receives heavy snowfall from November through April. South Fork Salmon River Road is a gravel route that may be rough or impassable in winter and spring. No facilities exist at the spring itself. The nearest reservable lodging is Johnson Creek Guard Station, a 1922-era cabin about 19 km away. Water temperature is scalding — test carefully before contact.
