Road construction may cause temporary closures
Resurfacing of the Loop Road and campground loops from 5/14-5/25 will temporarily close access to some parking lots. Be prepared for delays, pilot cars, and closures throughout this period.
If you intend to visit the caves, do not bring clothing or gear that has been in other caves. Obtain a free cave permit at the visitor center before entering any cave.
The Visitor Center is open daily from 8 a.m. until 6:00 p.m.
The Lava Flow Campground is open for camping and water is available in the campground from spigots and in the campground restrooms. The separate Group Campground is closed until May 26.
The physical address for the visitor center is 1266 Craters Loop Road, about half-way between Arco and Carey on US Highway 20/26/93. Please note that there is no access to the main visitor use area of Craters of the Moon by unpaved roads.
