Russian John Hot Springs

## Overview Russian John Hot Springs is a free, natural hot spring located in central Idaho's scenic Wood River Valley, near the town of Ketchum and the Sun Valley resort area. Situated at approximately 43.805°N, -114.585°W, the springs sit along the East Fork of the Big Wood River in the Sawtooth National Forest — a region renowned for its rugged mountain landscapes and geothermal activity. The springs take their name from "Russian John" (John Petranovich), a colorful 19th-century figure who was a Russian-born sheepherder and prospector in the Wood River Valley during the mining boom era of the 1880s. Russian John was well known in the area and became something of a local legend; the nearby Russian John Guard Station and campground also bear his name. Central Idaho sits along the edge of the Basin and Range geologic province, where deep faulting allows groundwater to circulate to significant depths, picking up heat from the earth's interior before rising back to the surface. This geothermal activity feeds a number of hot springs throughout the region, and Russian John Hot Springs is one of the more accessible examples. ## Directions 1. From Ketchum, Idaho, head east on Trail Creek Road (also known as Sun Valley Road / ID-75) and then south on ID-75 toward Hailey. 2. Turn east onto East Fork Road (Forest Road 118), following signs for the East Fork of the Big Wood River. 3. Continue along East Fork Road for approximately 6–7 miles. The Russian John Hot Springs area and the nearby Russian John Campground will be on your right, close to the river. 4. Look for a small pullout or parking area near the campground. The springs are a short walk from the road, near the riverbank. *Note: Road conditions may vary seasonally. In winter and early spring, East Fork Road may be snow-covered or impassable. A high-clearance vehicle is recommended during shoulder seasons.* ## What to Expect Russian John Hot Springs is a rustic, undeveloped soaking spot — there are no facilities, changing rooms, or fees. The hot water emerges from the ground and collects in one or more shallow, user-built soaking pools near the East Fork of the Big Wood River. Water temperatures can vary depending on the season and how close the pools are to the source, but soakers have historically reported temperatures warm enough for a comfortable soak, especially when blended with cooler river water. The setting is beautiful: the springs are surrounded by sagebrush-covered hills and forested mountain slopes typical of the Sawtooth National Forest. The East Fork of the Big Wood River runs nearby, and the area offers excellent views of the surrounding peaks. Wildlife sightings — including deer, elk, and various bird species — are common. Because the springs are free and relatively accessible from the Sun Valley area, they can attract visitors, especially on weekends and during the summer months. For a more peaceful experience, consider visiting on weekdays or during the off-season. The nearby Russian John Campground offers basic camping facilities for those who want to extend their stay. As with all natural hot springs, water quality can fluctuate and is not monitored. The springs have historically been used for soaking rather than drinking. Visitors should be mindful of Leave No Trace principles — pack out all trash and respect the natural surroundings to help preserve this special place for future visitors.
