Lava Flow Campground

Lava Flow campground is a quirky little campground, but it is by far the best place to camp to explore Craters of the Moon National Monument. You are within walking distance of the very informative Visitor’s Center. Sites vary widely in size and quality. We arrived early on a Friday and lucked into space #42 a long, level back-in site near the bathroom. There are maybe a dozen sites that will accommodate larger rigs, a few that are only good for tent/car campers, with the remainder falling somewhere in the middle.

The entire campground is first come/first serve so plan on arriving early if possible. The campground was full by late afternoon every day during our stay. The sites are $15 and you must self-pay at a kiosk with credit card (no cash/checks accepted). You can also only pay for one night at a time, so make sure to renew before heading out to explore the park. We did not see a map of the campground posted anywhere and it would have been extremely helpful. The sites are tucked in and around the natural volcanic rock formations. There are also a couple huge pull-through sites located on the opposite side of the road from the main campground. It’s hard to tell they are even campsites and we saw folks circle the campground and leave when they were empty.

Recycling is located across the road from the main campground, garbage is centrally located about the middle of the main campground. There are bathrooms (both flush and pit toilets), but no showers. Each campsite has a picnic table and grill, no ground/wood fires are permitted.

We had one bar of Verizon 1X which pretty much amounted to no cell service at our campsite. However, if we walked higher in the campground we did manage to get enough coverage to send/receive texts.

The landscape is otherworldly, which is really cool. The camp site’s are spacious and blend in well with the landscape. There are fresh water spigots throughout the campground, and plenty of trash receptacles. The bathrooms are sizable and clean. If you want/need cell signal or WiFi you might struggle. The campground does not offer WiFi and the cell signal is nearly nonexistent. We were able to use our AT&T Nighthawk and $30 MIMO antenna to get 10-15 mbps download speed but almost no upload.

Beautiful placement and layout of the campsites so they feel like they are a part of this unique landscape. Staying here is all about location and it is a gorgious one. Centralized water spigots are spread out throughout the campground. Bathrooms are spacious and clean, but lack of showers is a bummer.

Verizon 1-bar of 3G but even boosted with a WeBoost we found that it was useless.
LTE is available farther into the park but not at the campground or visitor center.

This isn't a large or spaced out campground but it is super convenient for seeing the park and getting the most out of your Craters experience. It is a short walk from the visitor's center and I highly recommend watching their 15 minute video about the park - very informative!

It is dry camping, the sites are paved and mine was level enough that I didn't need blocks. The sites when you first enter are larger than the ones further in. There are some pull-thrus (like 15).

My AT&T service was almost non-existent. Every once in a while I would get 1 bar, but I wouldn't count on it.

The bathrooms were clean but I didn't see any showers. The campground is also fairly close to the entrance road so it isn't as quiet as it could be if it were nestled further in the park. It fills up early so try to get there as close to check-out (12pm) as you can to grab a spot in the busy summer months.

I paid $7.50 with my Access pass, regular price is $15 during the summer months.

This campground is basically the only convenient place to camp when visiting Craters of the Moon National Monument, since the town of Arco is fairly distant and has extremely limited offerings. Sites are generally well-spaced, and we like the ambiance of the campsites nestled among the volcanic formations. As is typical for a national park campground, this is dry camping, with water available throughout the campground and pit toilets.

Payment for camping is exclusively through the kiosk located across from the staffed entry booth, so be sure to bring a credit or debit card. We weren’t able to figure out how to pay for more than one night at a time, so we needed to renew each morning for the duration of our visit. Most people only stayed 1-2 nights, so this isn’t a significant burden on campers.

We did find the campground layout to be a little unclear, and apparently other people did, too, based on the number of people who accidentally drove into our pull through site thinking it was the loop road. Sites are a mixture of pull-through and back-in, with a wide variety of sizes. Consult the map / site list at the kiosk to find a site that fits your needs. Two of the best sites for larger rigs are #1 and #2, on the left side as you enter the park. They are strangely located behind the entry booth, and are somewhat separated from the rest of the campground, but have nice long driveways and pretty good privacy.

It took us only one day of fairly slow wanderings to see the exhibits and most of the trails in the park, so this is definitely a park that can be visited quickly if needed. Be sure to bring all your necessary groceries since Arco is far away and has few restaurants or stores. There is a free dump station in Arco at the Conoco station which is open from April through October.

AT&T Internet: We had no service on small devices like phones and tablets, but our MyFi picked up 1 bar of LTE service which proved to be surprisingly solid and fast.

As other reviewers have stated, this is a nice campground right in the monument and the best way to enjoy your visit. During my visit the end of July most people would stay one night and leave early. To get a good site you need to arrive early afternoon especially if you have a larger rig as those sites are limited. Overall it's a typical campground experience but reasonably priced and very convenient.
