About Kirkham Hot Springs
Kirkham Hot Springs is a series of natural soaking pools and small steaming waterfalls along the South Fork Payette River, located within Kirkham Campground/Day Use Area on Highway 21 in the Boise National Forest, about 3 miles east of Lowman, Idaho. A staircase trail leads down from the roadside parking area directly to the river's edge, where hot spring water mixes with the cold river to form a natural riverside swimming hole.
The site sits at about 4,000 feet elevation along Highway 21 (the Ponderosa Pine Scenic Byway) right next to the South Fork Payette River, within a developed USFS campground that offers little shade and scattered Ponderosa pines, described by the Forest Service as hot and sunny in summer.
Swimming at Kirkham Hot Springs
Visitors soak in a series of natural rock pools at the river's edge fed by small steaming hot-spring waterfalls, where hot mineral water can be mixed with the cooler river current to adjust temperature; it functions as a soaking destination rather than a swim-lap spot, accessed via a staircase from the parking area.
How to get to this swimming hole
From Lowman, Idaho, drive east on State Highway 21 (Ponderosa Pine Scenic Byway) about 3 miles to the signed Kirkham Campground/Day Use Area on the right, next to the South Fork Payette River; a staircase trail from the parking area leads down to the soaking pools.
Parking: Roadside parking at the Kirkham Campground/Day Use Area off Highway 21; a Recreation.gov day-use confirmation number must be displayed on the vehicle dashboard, and illegally parked vehicles can be fined or towed.
The hike in
- Time on foot
- a few minutes each way
Difficulty: easy, short staircase only, negligible distance or elevation change
Trailhead: Kirkham Campground/Day Use Area parking lot, directly off State Highway 21 (Ponderosa Pine Scenic Byway) about 3 miles east of Lowman, ID.
This is not a backcountry trail hike, official sources (Recreation.gov, Visit Idaho) describe a staircase that drops directly from the highway-side parking area down to the river's-edge soaking pools. No source gives an exact step count or mileage, so it should be treated as a very short walk, not a hike. Note this is distinct from the separate 'Kirkham Ridge Trailhead' about 0.7 mi away, which serves a longer trail up the ridge and is not needed to reach the pools.
Hazard warning: rocks near the pools are uneven and can be slick when wet (Recreation.gov Activity Pass page).
