What Should You Know Before Going to Baumgartner Hot Springs
Baumgartner Hot Springs feature a large developed soaking pool and several natural pools along the South Fork Boise River, making them one of the most accessible and family-friendly hot springs in southern Idaho. The water emerges from the hillside at about 110°F (43°C) and cools slightly before entering the main pool, where it stays between 101°F and 110°F (38–43°C) — warm enough for a relaxing soak, yet safe even for families.
The site includes restrooms, picnic tables, and a campground managed by the U.S. Forest Service, offering both convenience and a natural atmosphere. The campground has shaded sites, potable water, and fire rings, and it’s open during the warmer months.
Visitors should note that day-use access is permitted only when the campground is open, typically from late May through mid-September, depending on weather and maintenance. The pool area can get busy on weekends, so arriving early in the morning or on weekdays ensures a quieter experience.
For day-use visitors, the hot springs are accessible during the same period, but no reservation is needed. A small entrance fee (about $5 per vehicle) applies, payable on-site. The area is closed during winter due to snow.
Please follow Leave No Trace principles — no glass containers are allowed, and soap or shampoo use in the pools is strictly prohibited.
