Willow Creek Hot Springs is a series of hot spring pools in the picturesque Alpine Valley, hidden within Idaho's Sawtooth National Forest at an elevation of 5,200 feet. The springs offer a rejuvenating soaking experience in a beautiful natural setting.

The hot springs are located 0.8 miles from the Willow Creek Transfer Campground. A small parking area sits just north of the campground at the trailhead. The trail is well-maintained and moderate in difficulty.

Willow Creek Hot Springs Mineral Pools & Soaking

The hot spring consists of a series of volunteer-built rock-and-sand pools set along a gravel bar of the creek. Hot mineral water emerges from the source at temperatures over 135°F (57°C) and flows down into each pool.

Depending on the season, soaking pool temperatures typically range from 96°F to 110°F (36°C to 43°C), and algae levels vary from pool to pool.

The remote corner of the Sawtooth National Forest around Willow Creek Hot Springs offers quiet wilderness and plenty of adventure:

Scenic drives and viewpoints – Forest roads lead to expansive views of hills, pine forests, and rugged Sawtooth foothills. Pullouts and meadows are perfect for photography, picnics, and wildlife.

Hiking and nature walks – Beyond the 0.8‑mile trail to the hot springs, the surrounding forest is dotted with short spur trails, gentle ridgelines, and dispersed routes ideal for casual hiking. Wildflowers, fall colors, and big‑sky vistas make this a rewarding area for slow exploration.

Wildlife watching and birding – Deer, elk, and occasionally moose roam the area. Raptors soar above slopes, and songbirds frequent the creek.

Fishing and creek exploration – Small creeks offer peaceful banks for wading and photography. The area isn’t a major fishing spot, but nearby streams may hold fish—check current Idaho regulations.

Willow Creek Transfer Camp has four large camping areas with amenities including picnic tables, fire rings, utility tables, and a vault toilet.

Trinity Hot Springs, 13 miles west, offers a range of accommodations, including lodge rooms, cabins, a separate house, and a campsite for both tents and RVs.
