About Boat Box Hot Spring

Boat Box Hot Spring, nestled along the Salmon River in Idaho’s Sawtooth National Forest, offers an unmistakably rugged soak experience. This primitive hot spring features a metal tub warmed by natural geothermal water reaching around 110°F, inviting you to relax while surrounded by untouched wilderness and the soothing sounds of flowing river water.

Getting There

Located just off Idaho State Highway 75, about 3 miles from Stanley, you can reach the spring with ease by car. From the ample parking area, a short 5-minute walk along a dirt path leads you to the hot spring, making it one of the more accessible hot springs in Idaho’s backcountry.

What to Expect

Boat Box Hot Spring captures the essence of primitive soaking with its single, hand-fed metal tub set into the riverbank. The water stays warm and inviting, but the site often draws crowds, so expect to share the space with other visitors. Facilities are minimal, so you soak surrounded by nature’s raw beauty, hearing the river ripple nearby.

Tips for Visitors

Visit during quieter times, like early mornings or weekdays, to avoid the busiest crowds. Bring sturdy shoes for the short walk and pack out all trash as there are no facilities. Since there’s no fee, respect the area by keeping noise low and preserving the natural environment while enjoying this authentic Idaho swimming hole.
