Craters of the Moon National Monument and Preserve

18 miles West of Arco on Hwy 20/26/93

Craters of the Moon is a vast ocean of lava flows with scattered islands of cinder cones and sagebrush. We invite you to explore this "weird and scenic landscape" where yesterday's volcanic events are likely to continue tomorrow..

Described as a "weird and scenic landscape", Craters of the Moon certainly lives up to its reputation. It was established in 1924 to preserve the unique volcanic features of this enormous lava field. The 750,000-acre monument contains a diverse array of volcanic features including volcanic rifts, cinder cones, spatter cones, shield volcanoes and lava tube caves. A surprising number of plants and animals have adapted to live in the harsh volcanic and high desert environment. It is an excellent site for hiking, bird watching, photography, backpacking and caving (permits required). The monument is cooperatively managed by the National Park Service and Bureau of Land Management. Summer activities include guided cave walks and evening programs at the campground. Winter activities include Winter Ecology Workshops, snowshoeing, and cross-country skiing. School groups are welcome to visit the monument and curriculum resources for teachers are available on our website. Teachers' workshops are also offers.

Arrived late, self registered and enjoyed the usual clean facilities, pull through with electrical and your own little swath of grass and fire pits for those that want it. Friendly staff who even refunded a few bucks of our fee for AAA discount after the fact, with good advice. Lovely made-for-you waffles and self serve coffee hot the spot. Good location for freeway on our way to Yellowstone. Burger/Cafe joint just up at the corner for the lazy in the morning or evening. Effortless to stay the night.

Awesome! You could never imagine how big this place is. The visitor center is great, be sure to fill up your water bottles there before you leave. Check out the lava caves. Bring a strong flash light.

Dont let Arco scare you away from a great KOA. It may seem out of the way or sketchy getting there. The owners are awesome. Great ice cream social, good selection of beer and wine in the store. Good pool, clean bathrooms and clean cabin. Super nice people.

Amazing service. The owner is charming and sweet. They offer a free waffle breakfast daily as well as a very affordable ice cream social every night at 6 for only $1.00 per scoop. Laundry, a shower, and a small but appreciated pool. With 4 kids, it was a perfect stop.

The people here are super friendly, that's what kept this rating from being lower. Also, free waffles and coffee for breakfast! Unfortunately there are some areas in which they could improve. Cleanliness is one. The bathrooms are a little outdated with weird stains on the floor and weird smells. There was also a disposable washcloth on the floor of one of the showers that was there for more than one day, and didn't get cleaned up when they cleaned the bathrooms. The showers are also really small and the curtain is basically touching you the whole time. Also, the site I camped at had a dog poo on one side of it. It was there when I got there, don't know for how long. But I guess they don't check sites for garbage between guests? And there were awful biting flies in the area that were drawn to the dog poo then came for me. Overall, an okay place to spend the night while traveling, but past that I wouldn't recommend.
