Alkali Lake Hot Springs is one of the numerous hot springs of Long Valley Caldera located near Warm and Big Alkali Lakes.
The hot mineral water gushes out of the Earth’s crust at a temperature of 135°F, hundred yards away from Warm Lake and a parking area. The source is covered by a large corrugated metal pipe. The hot water is transferred through a plastic pipe into a shallow concrete tub 50 feet away. The water cools down a little but still can be too hot to bathe. If it is too hot, water could be diverted and cooled.
Currently, these hot springs do not provide the best soaking experience but it is located near a highway and available year-round.
