Current Conditions - Craters of the Moon

Loop Road and all Facilities are Open

The visitor center is open daily from 8 a.m. - 6 p.m.

All caves are now open. Please obtain a required permit from the visitor center before entering any cave. In order to prevent the introduction of a bat-killing fungus into our caves, permits are only issued to parties that do not have any clothing or gear that has been in other caves outside of Craters of the Moon. Please observe caution in Beauty and Boy Scout Caves because some snow and ice are still present in these caves.

The Lava Flow and Group campgrounds are open and water is on.
