About this spring
USFS concrete soaking pool built by the CCC in the 1930s at the end of Granite Creek Road (~7,000 ft), perched above Granite Creek Falls at the edge of the Gros Ventre Wilderness — 45x75-ft pool ~93°F summer, up to ~112°F winter. In winter, access by snowmobile/ski/dogsled only. Fee: ~$12 adult / ~$7 child, cash only. Cash only; no cell; winter wheeled access prohibited — snowmobile/ski/dogsled only.
At the end of Granite Creek Road in the Bridger-Teton National Forest, about 30 miles southeast of Jackson, this concrete soaking pool is one of the Forest Service's more unusual recreation sites. Early settlers dug a pool to collect the spring water, and the Civilian Conservation Corps enhanced it in 1933, adding the deck, changing room, and campground still in use. Perched near Granite Creek Falls at roughly 7,000 feet, the pool runs in the mid-90s in summer and can reach 112°F in winter — though during peak spring snowmelt the temperature can sag into the 80s. In July 2007 the Granite Creek Fire blackened more than 1,700 acres around the springs.
Access changes completely with the seasons: drivers reach the pool in summer via the gravel canyon road, but once snow closes the road, visitors arrive only by snowmobile, ski, snowshoe, or dog sled. A concessionaire collects a cash-only fee (about $12 per adult), and there is no cell service or potable water on site.
Directions & trailhead access
US-189/191 east from Hoback Junction up Hoback Canyon, then Granite Creek Rd ~10 mi to road's end (~34 mi SE of Jackson).
Wyoming geothermal context
Wyoming holds the planet's densest geothermal field in Yellowstone — nearly all of it legally protected and off-limits to soaking. The visitable thermal water is outside the park: Thermopolis' free state bathhouse, river-edge springs along the North Platte, and scattered backcountry seeps in grizzly country where bear-aware travel is mandatory.
What a developed site means here
A developed site sits between primitive and resort: improved soaking infrastructure — built tubs, decks, stairs, sometimes changing rooms or vault toilets — often run by a land trust, nonprofit, or small operator. Expect modest fees or donation requests, posted etiquette rules, and more predictable conditions than a wild pool.
Best time to visit
Year-Round (Best: May – October)Pool temperatures and access can change with weather and season. Outdoor ambient temperatures fluctuate significantly across Wyoming. Late spring through autumn offers the most comfortable road access.
