Cute campsite/RV Park. Nothing is around, so bring food and activities! The store is really cute, they serve ice cream in the evenings and pancakes for breakfast. Nice touch, since there isn’t much else around. Small pool, but it’s great after a hike in the park.
We stayed here on our way to Yellowstone. Has most of the usual KOA amenities: clean bathrooms, pool, cabins, full hookup RV spots, and a few tent spots. Even has a couple of teepees. Very friendly staff and a well stocked store/deli. Near Craters of the Moon National Monument. The town of Arco was charming and has an interesting history as the first nuclear-powered city in the US. If our travels take us this way in the future we'll camp here again!
