Campers reach this 42-site campground via a paved road directly at the entrance to Craters of the Moon National Monument, though some reviewers note rough access conditions on interior loops. The National Park Service operates this first-come, first-serve facility year-round, with sites turning over at 2 PM during busy periods. Payment requires a credit card at an automated machine, as cash is not accepted.
The campground sits entirely on volcanic terrain, with sites carved around existing lava rock formations that create natural windbreaks and privacy barriers. Annie C. found her site "set up between some lava rocks to get some semblance of a wind break" where she "could not see any other sites from inside my tent." Sites vary dramatically in size and configuration, from pull-through spots suitable for RVs to tucked-away tent areas. The farthest loop accommodates smaller rigs only due to tight turns.
Hiking trails connect directly from the campground to the park's 7-mile scenic drive, providing access to cinder cones, spatter cones, and lava tube caves. The North Crater Flow trail starts from camp, while Inferno Cone offers elevated views for those willing to climb. Free cave permits are required from the visitor center. Water access is restricted during peak season—RVs cannot fill tanks, though personal water containers are allowed.
Facilities include flush toilets and cold water sinks, but no showers or hookups. Campfires are prohibited throughout the lava field. Cell service is limited to nonexistent, even at the visitor center. Water service shuts off during winter months, reducing rates to half price. Sites 1-5 sit directly adjacent to the entrance station, while sites 34, 35, and 42 offer accessibility features.
For tent campers needing more traditional ground surfaces, tent sites near Craters of the Moon National Monument provide alternatives beyond the volcanic landscape.
