About Slate Creek Hot Spring
Slate Creek Hot Spring, also known as Hoodoo Hot Spring, Idaho is a free backcountry geothermal spring in the Sawtooth National Recreation Area in the White Cloud Mountains of Custer County, near the town of Stanley. The spring feeds a soaking box at the site of the old Hoodoo mines at an elevation of 7,047 feet. Visitor reports describe the water temperature as comfortable for soaking. Stanley, a small mountain town at the headwaters of the Salmon River, is the nearest community with services.
The spring sits along Slate Creek, which drains from Hoodoo Lake higher in the White Cloud Mountains and flows into the Salmon River. The old mining equipment and structures from the Hoodoo mines are visible around the spring, adding historical character to the soaking experience. Hoodoo Lake, an alpine glacial lake at 8,678 feet, is accessible by continuing past the hot spring on a steep unmaintained trail. The White Cloud Mountains are part of one of the most scenic ranges in Idaho, with dramatic granite peaks, alpine lakes, and remote backcountry trails.
The soaking box is visitor-maintained. Conditions vary with season and use. No facilities exist at the spring.

Suitability & Accessibility
Who Should Visit Slate Creek Hot Spring
Slate Creek Hot Spring suits experienced hikers seeking a scenic backcountry soak in the White Cloud Mountains with the added interest of historic mining relics.

Good hiking shoes and a sense of adventure are essential, as the trail conditions can be rough.
