Pete Creek Hot Springs, also known as Vaughn Hot Springs, is a scenic geothermal spot along the Middle Fork Boise River, located right off the road. It sits about 35 miles north of Idaho City and 30 miles west of the historic mining town of Atlanta.

Hot mineral water flows down the hillside and plunges into the river, creating a unique soaking experience surrounded by Idaho’s forested landscape. Visitors may also spot local wildlife, including deer, elk, foxes, and a variety of birds.

Although the springs are close to the road, reaching the soaking pools requires some effort. To access the pools, you must ford the Middle Fork Boise River. From late August to early October, you can cross directly from the road to the waterfall. Alternatively, walking 300 feet downstream provides an easier crossing.

⚠️ Caution: Fording the river can be very dangerous if done incorrectly. High water and strong currents can sweep you away, and river rocks may be unstable or slippery. Only attempt to cross if you are confident and experienced.

There are no amenities at this location. Bathing suits are highly recommended since the pools are visible from the road.

Pete Creek Hot Springs Experience

The main hot mineral waterfall cascades 30 feet into a pool at the cliff’s base. Volunteers have constructed the pool from rocks arranged in a circle to capture geothermal water. Its size is generally around 15×10×3 feet, though it varies with the season. Higher river levels can wash the pool out, so it often needs to be rebuilt each summer.

A smaller soaking pool, called Eagle’s Nest, sits near the top of the cliff and accommodates two people. You can spot it from the road by a rock wall with a white PVC pipe. Unlike the lower pool, Eagle’s Nest is isolated from the river and is not washed out by seasonal runoff. To maintain it, please drain the pool before leaving to prevent algae growth. Reaching Eagle’s Nest requires climbing up the cliff.

Water temperature varies throughout the year and with river levels, ranging from 100°F (38 °C) to 138°F (59°C) . Eagle’s Nest is generally hotter than the main pool. You can adjust its temperature by moving rocks to divert the water flow.

The Middle Fork Boise River is home to several other wild hot springs. Nearby spots include Smith Cabin Hot Springs, Loftus Hot Springs, and Sheep Creek Bridge Hot Springs, each offering primitive pools in scenic forested settings.

Closer to Atlanta, are additional geothermal sites such as Atlanta Hot Springs, Chattanooga Hot Springs, and the Power Plant Recreation Area. These undeveloped pools are often tucked into rugged landscapes, perfect for backcountry soaking.

Beyond soaking, the river is popular for fishing, with rainbow trout, cutthroat trout, brook trout, and mountain whitefish. Hikers and nature lovers will enjoy numerous trails, wildlife viewing, and the peaceful riverside scenery along the Boise National Forest.
