Located in the Sawtooth National Forest near Stanley, the Elkhorn Boat Box Hot Springs are unusual and unique hot springs because when the natural springs submerge during the spring run-off, the warm water can still be enjoyed in a wooden soaking box tub that is usable all year long. The riverside hot tub must be filled with water and the temperature adjusted by bringing cooler water in with a bucket, and it comes with sunken seating for additional comfort. When the river is low, there are one or two seasonal pools that have scalding hot 136°F water that is cooled by the river water, making for a relaxing spot. The pools are near the eastern Sawtooth trailheads and are easily accessed by hiking.
