About this spring
Esmeralda County-managed hot well near Dyer, Nevada — a ~12x6 ft concrete soaking tub (~105°F) with handrails and cinder-block enclosure, fed by an artesian geothermal well drilled in the 1880s. Overflow ponds attract waterfowl beneath views of Boundary Peak. Vault toilet, fire rings, grills on site. No cell service. County warns vandalism could force permanent closure. Endangered Fish Lake Valley tui chub lives in valley waters.
Fish Lake Valley Hot Well is not a natural spring at all but an artesian geothermal well: ranchers drilling for oil in the 1880s struck hot water instead, and the casing was later developed into a concrete soaking tub. The main gravel-bottomed pool — 12 by 6 feet, rimmed by a cement deck — receives a strong artesian flow of more than 50 gallons per minute at about 105°F, then overflows into a man-made swimming hole stocked with large goldfish, which in turn feeds second and third ponds; temperatures step down across the ponds from roughly 105 to 85°F. The site sits at 4,800 feet in open Fish Lake Valley ranch country near Dyer, with the White Mountains and 13,146-foot Boundary Peak — Nevada's highest summit — and the Boundary Peak Wilderness in view. Pit toilets, trash receptacles, barbecue pits, parking and free primitive camping make it one of western Nevada's better-equipped free soaks.
Directions & trailhead access
From the NV-264/NV-773 junction south of Dyer, NV-264 ~5.8 mi to the dirt road on the east side; ~7 mi graded dirt, keep left at the fork, to the springs.
Nevada geothermal context
Nevada has more hot springs per square mile than any other state — Basin and Range faulting brings deep thermal water to the surface across nearly every valley. Most sites are primitive seeps and tubs on public BLM land reached by long, unmaintained dirt roads. Carry extra water, and watch for flash floods in desert washes during storms.
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
October – April (Fall, Winter & Spring)Desert thermal zones experience high summer ambient heat. The cooler months from late autumn to early spring offer the most refreshing ambient conditions for open-air soaking.
