Hot Springs

Russian John Hot Spring sits on a sagebrush bench just west of Idaho Highway 75, about 18 miles north of Ketchum in the Sawtooth National Recreation Area. It is on Sawtooth National Forest land, it is free, and there is no permit or day-use fee. Maps and some guidebooks call it Russian John Warm Spring, and that name is the more honest one. Water leaves the source at roughly 89°F and the pool usually holds at 86°F or a little less, depending on the air temperature and how many people have been in it. On a cool spring evening it feels closer to a bath that has sat too long. On a hot July afternoon after a ride on the Harriman Trail it is about right.

The turnoff is on the west side of the highway, a couple of miles north of the Baker Creek Road junction and around milepost 146. A short dirt spur (Forest Road 913) climbs to a small gravel parking area above the road. From there a footpath runs about 100 yards up the slope to the pool, so the walk takes a few minutes. Some listings put the pool 1000 yards from the highway, but the parking area, the trail and the pool all sit within a few hundred yards of the pavement.

The pool is small. It is a shallow basin with low rock walls held together with mortar and a sandy, clay-and-rock bottom, and it fits two to four people comfortably. Warm water seeps up through the sand rather than pouring in from a pipe. The chemistry is a mild, alkaline sodium silicate water with little or no smell. Because the water is only lukewarm, it grows algae, and early in the season after a winter of light use there can be green strands on the walls and silt that clouds up when you move. Expect some mud on your feet. There is a bench and a fire ring beside the pool. Check current fire restrictions for the Sawtooth National Forest before lighting anything, since summer fire bans are common here.

The view is the reason most people stop. The pool faces north up the Big Wood River valley toward the Boulder Mountains, which stay streaked with snow well into summer. Deer and elk use the meadows below.

Summer and early fall are the best times to soak. The spring is reachable all year, but the pullout can be buried by highway plowing in winter, so plan on parking elsewhere and walking or skiing in. The Harriman Trail, an 18-mile gravel path between the Sawtooth NRA Headquarters and Galena Lodge, runs along the valley floor a few hundred yards away, and the Blaine County Recreation District grooms it for Nordic skiing in winter. Be ready for a cold climb out of lukewarm water when the air is below freezing.

About a quarter mile away is the Russian John Guard Station, a Forest Service site set aside as a ranger station in 1908. Its current buildings went up in 1934 and are listed in the Civilian Conservation Corps in Idaho collection. The buildings are not a public facility, so leave them alone.

Camping is not allowed at the spring. The closest developed option is Easley Campground, about 4 miles south on the Big Wood River, with ten first-come sites. Wood River Campground (about 10 miles north of Ketchum, 30 sites) and North Fork Campground (8 miles north of Ketchum, 28 sites, most reservable) are a little farther south along Highway 75.

Clothing is optional by long custom, so expect that and don't be surprised by it. The pool is small, so if it is full, wait your turn or come back later. Pack out every can and cigarette butt, skip the soap and shampoo, keep glass away from the pool, and keep dogs out of the water. The spring gets heavy use in summer, and a small pool like this one shows every bit of trash.

Be careful. Pay attention to posted signs and always test the waters before you get in. Some hot springs can get up to boiling temperatures. Be sure to drink plenty of water to combat the dehydrating effect of the spring.
Be respectful of other soakers and the hot spring. Don't hog the pool. Camp at least 200 yards away and keep fires in designated areas. Keep your pets out of the water and never pee in thermal feature. Glass bottles should never go near a hot spring.
