Hot Creek is a geothermal stream in the Inyo National Forest in Mono County that begins its course as Mammoth Creek in the eastern Sierra Nevada. Originating an outflow from the Twin Lakes south of Mammoth Mountain, the stream arises from melted snow water at 8,500 feet above sea level and as it leaves the Sierra and flows east into the Long Valley Caldera, it is warmed by water from geothermal springs at the Hot Creek State Fish Hatchery.

From here, the stream becomes Hot Creek and becomes warmer as numerous hot springs join the creek in the Hot Creek Gorge. The Hot Creek Gorge area of Hot Creek and its mineral pools is managed by the U.S. Inyo National Forest and offers an array of activities such as swimming, fishing, birdwatching, and photography.
