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
