A unique and memorable experience for young and old. Named for its other-worldly atmosphere, the Craters of the Moon thermal area sprang up in the 1950s when the nearby power station lowered underground water levels. As hot water was withdrawn from deep within the field, the water level in the deep reservoir dropped and the remaining water boiled more violently, producing more steam. Large quantities of this extra steam escaped at Craters of The Moon. Enjoy this fantastic geothermal area long well-formed pathways and with elevated viewing platforms. You'll see interesting plants that have adapted to thrive in the hot steamy conditions. 45+ minutes walk.
