Lava Hot Springs World Famous Hot Springs

Bubbling out of natural underground springs, the hot water is laden with minerals, but has no sulfur odor. Over 2.5 million gallons a day flow through the hot springs and are diverted into the Portneuf River keeping the springs ever changing and clean. The spring's temperatures range from approximately 102˚ F to 112˚ F degrees.  Our hot pools have a snow melt system in the deck around them, a cold water deck shower and canopies to block the sun or rain.

YOU CAN PURCHASE PASSES ONLINE OR WHEN YOU ARRIVE

Please see our CALENDAR for different hours for the Hot Pools and the Swimming Pools.
