Sawtooth Lodge Hot Springs

## Overview Sawtooth Lodge Hot Springs is a remote geothermal spring located deep in the heart of Idaho's Sawtooth Mountains, at an elevation near the rugged wilderness that defines this iconic region. Situated at approximately 44.16°N, 115.17°W, the springs are found in the general vicinity of Grandjean, Idaho — an area long celebrated for its natural hot springs and pristine backcountry. The Sawtooth Range and surrounding Sawtooth Wilderness and Sawtooth National Recreation Area are home to numerous geothermal features, fed by deep volcanic and tectonic activity along the Idaho Batholith. Historically, the hot springs in this part of central Idaho have been used by travelers, miners, and outdoor enthusiasts for well over a century. The name "Sawtooth Lodge" suggests a connection to the historic lodges and outposts that once served as base camps for adventurers heading into the Sawtooth backcountry. While specific historical records for this particular spring are limited, the broader Grandjean and Sawtooth area has been a destination for soaking in natural hot water since at least the late 1800s. The water at Sawtooth Lodge Hot Springs has historically been enjoyed for soaking, and visitors have reported that the geothermal pools offer a relaxing experience amid stunning mountain scenery. As with many backcountry hot springs in Idaho, the water temperature and flow can vary seasonally. ## Directions 1. From Boise, Idaho, head north on ID-21 (the Ponderosa Pine Scenic Byway) toward Lowman. 2. Continue on ID-21 past Lowman, heading northeast toward Stanley. 3. Approximately 7 miles past Lowman, look for the turnoff to Grandjean (Forest Road 524) on the left (west) side of the highway. 4. Follow Forest Road 524 (a gravel/dirt road) for roughly 6 miles toward the Grandjean area. 5. The hot springs are located near the historic Sawtooth Lodge site in the Grandjean area. Watch for signage or pull-offs near the South Fork of the Payette River. *Note: Forest Road 524 may be seasonal and could be impassable during winter and early spring due to snow. A high-clearance vehicle is recommended. Check current road conditions with the Sawtooth National Forest before heading out.* ## What to Expect Sawtooth Lodge Hot Springs is set in a remote, forested mountain environment surrounded by towering peaks and dense conifer forests. Visitors can expect a rustic, backcountry soaking experience — there are no developed facilities or commercial amenities at the springs themselves. - **Water & Soaking:** The geothermal water feeds into natural or semi-improved pools. Water temperatures can vary, but hot springs in this area are commonly reported in the range of 100–110°F (38–43°C). Cooler creek water may be available nearby to mix for a comfortable soak. - **Scenery:** The surrounding Sawtooth Mountains provide a dramatic backdrop, with granite peaks, alpine meadows, and the South Fork of the Payette River nearby. - **Access:** The road to Grandjean is unpaved and best suited for high-clearance vehicles, especially later in the season. The springs are generally accessible from late spring through fall, depending on snowpack. - **Crowds:** Due to its remote location, the springs tend to see fewer visitors than more accessible Idaho hot springs, offering a more peaceful and secluded experience. - **Seasonal Notes:** Late summer and early fall typically offer the best access and most comfortable conditions. Spring runoff can affect both road conditions and pool temperatures. This is a true backcountry hot spring — visitors should come prepared for remote conditions, pack out all trash, and respect the natural environment.
