Pine Flats Hot Springs

Pine Flats Hot Springs is a thermal spring on the bank of the South Fork Payette River in Boise County, Idaho, within the Boise National Forest. USGS lists the feature as Pine Flat Hot Springs. It sits below Pine Flats Campground, a Forest Service site a few miles west of Lowman on the Banks-Lowman Highway, also known as the Wildlife Canyon Scenic Byway. The campground lies at about 3,700 feet under tall ponderosa pines, and the river below it is used for trout fishing, rafting and kayaking.

From Boise, State Highway 55 runs about 38 miles north to Banks, and the Banks-Lowman road continues east 28 miles to the campground. A quarter-mile nature trail starts in the campground and leads to the spring at the river's edge. Recreation.gov lists a $5 day-use fee for vehicles entering the campground. The campground has 24 sites with vault toilets, drinking water and paved spurs, with nightly fees of $15 for a single site and $30 for a double. The Forest Service lists the season as May 19 through September 30. After that date the area is open to dispersed camping, with no water, trash or toilet service, and the campground gate closes for winter.

In 2026 the Boise National Forest closed the campground area and road from May 12 through June 30 while crews felled hazard trees. In 1989 the Lowman Fire burned in the South Fork Payette drainage near Lowman from late July to the end of August. Lowman is the nearest community, and the Lowman Ranger District answers questions about the site. The Danskin River Access lies 5 miles west of the campground, and the Forest Service notes several other natural hot springs along the same byway.
