Trego Hot Springs flow into a hand-dug hot pond on public land at the edge of the Black Rock Desert. The springs are located in relative isolation about 16 miles down a gravel road with virtually no sign of civilization aside from the nearby railroad track.
Hot water bubbles into the cool pond from several places and creates very hot pockets amongst very cold pockets, and the location of the warm outlets depend on the spring's mood on any given day. The temperatures mix a little better on windless days, and it is possible to swim or wade in the pond, which fluctuates from about 2 feet to 3.5 feet deep, to find an area with ideal temperatures. On windy days, the water movement is such that cold and hot pockets of water interact much more fluidly, and maintaining an ideal temperature may become a little more labor-intensive.
Water flows from the main source, located at one tip of the Y-shaped pond, at temperatures too hot to touch. Temperatures vary throughout the rest of the pond and become cool the further from the source you venture. The pond is mildly sulphur-smelling, and the bottom of the spring is an extremely slimey silt; be warned that this will find its way EVERYWHERE, including any clothes, gear or vehicles you use to visit the springs.
These springs can get very busy during the week that Burning Man is held, though its isolated location ensures that it rarely receives crowds the remainder of the year. High-clearance vehicles are strongly recommended for the gravel road between NV-447 and the springs. Be aware that the last 0.5 miles to the spring can become incredibly muddy if there has been any recent rain, so you may want to consider parking on the gravel road and walking the last stretch to the springs. There are no services near the springs, and only a gas station and two bars in Gerlach. Also, be aware that the adjacent railroad track is a live track.
