Kirkham Hot Springs

Nestled along the South Fork of the Payette River in the heart of Boise National Forest, Kirkham Hot Springs is a crown jewel of Idaho’s geothermal wonders. Just 2 hours from Boise and easily accessible via Highway 21 (Ponderosa Pine Scenic Byway), this year-round destination offers cascading thermal pools, serene river views, and a rejuvenating escape for adventurers, families, and solo travelers alike.

Key Features & Highlights

• Natural Terraced Pools: Soak in mineral-rich waters flowing down volcanic rock terraces, creating tiers of pools with temperatures ranging from 100°F to 112°F. Mix hot and cold water by adjusting your proximity to the river’s edge.

• Scenic Beauty: Surrounded by evergreen forests and the rushing Payette River, Kirkham’s postcard-worthy setting includes a small thermal waterfall perfect for a soothing shoulder massage.

• Accessibility: A short 0.1-mile walk from the parking lot leads to the pools, making it ideal for all skill levels. While the campground offers ADA-friendly paths, the short trail to the pools has some uneven and potentially slippery terrain.

Kirkham Campground: Stay overnight at the adjacent campground (seasonal May–October), which has vault toilets, picnic tables, and river access.

Activities & Tips

• Best Times to Visit: Avoid crowds by arriving early or visiting on weekdays. Winter offers a magical experience with steam rising over snow-dusted rocks.

• Nearby Adventures: Pair your soak with hiking the Kirkham Ridge Trail, fishing for trout in the Payette River, or exploring other nearby hot springs such as Bonneville and Pine Flats.

• Family-Friendly: Shallow pools and warm waterfalls make this a hit with kids (supervision advised near river currents).

• Pack Smart: Bring water shoes, towels, and a picnic. There are no fees for the hot springs, but a $5 day-use parking fee applies. Parking is limited—arrive before 10 AM on weekends.

Pro Tips for Conservation
Kirkham’s popularity means Leave No Trace principles are critical. Pack out trash, avoid soap in pools, and respect quiet hours if camping. Dogs are welcome but must be leashed at all times and kept away from the hot spring pools and runoff areas. Be sure to cleanup after your pets.
