About the Hot Well
Fish Lake Valley Hot Well, Nevada is a free county-managed geothermal spring near Dyer in Esmeralda County, set in the Fish Lake Valley between the White Mountains and the Silver Peak Range. The spring originates from an artesian well drilled by ranchers in the 1880s and has been developed into a concrete soaking tub approximately 12 by 6 feet and 3 feet deep, fed by around 50 gallons per minute at about 105 degrees Fahrenheit. A low cinder block wall and handrails enclose the tub. The site has a vault toilet, fire rings, and grills, making it one of the better-equipped free primitive hot spring sites in Nevada.
The tub overflows into a man-made pond stocked with goldfish, which connects to a second cooler pond. The ponds attract coots, waterfowl, and other wildlife that use the spring as a water source in the surrounding dry desert. Dispersed camping is permitted at least 100 feet from the spring. Esmeralda County has made ongoing improvements to the site.
Views from the tub include Boundary Peak to the west, Nevada's highest point at over 13,000 feet, the White Mountains along the California border, and the Silver Peak Range to the east. For visitors looking for natural hot springs near Tonopah Nevada, this is the most developed free option in the region and a reliable soaking destination year-round.

Safety & Etiquette
Fish Lake Valley Hot Well Safety Tips
The site maintains a soaking tub at around 105 degrees Fahrenheit.

Take breaks of 10 to 15 minutes, drink water before and after, and avoid soaking in peak afternoon heat in summer. Summer air temperatures in Fish Lake Valley can exceed 90 degrees Fahrenheit, which combined with the water temperature creates significant heat load. Early morning or evening visits are more comfortable from June through August.
Guests with cardiovascular conditions, high blood pressure, pregnancy, or serious skin or circulatory conditions should consult a doctor before soaking. The tub temperature can vary with flow rate and seasonal conditions, so always test before entering. A sign at the site warns that continued vandalism and killing of wildlife could result in permanent closure. Do not disturb the goldfish, coots, or other wildlife in or near the ponds.
