Indian Wells campground is located within the monument. The sites are geared for tenters, but there are sites that rv's can pull adjacent to. The restrooms are simple, and there is piped water. The highlight of this location is the monument itself. A number of lava tubes (caves) to explore. The lava tubes also provide great relief from the high summer temps. Would visit and stay again. We camped here in a Travel Trailer.
We stopped here because it is Passport America. There are about 30 sites and there were only two of us there. Nice, level, grass sites with full hookups, but no amenities. They don't have WiFi, which we need, but we only had to go about a block to the office parking lot to get it. We spent July 4th here and enjoyed it very much. We went to the "Demolition Derby" and watched the fireworks right outside our rig. We even had an air show each morning with an old double winged crop duster flying low right near our rig. Not much to do in Tulelake, but Klamath Falls, OR is just 20 miles away with WalMart and other stores and restaurants. We liked the peace and quiet so much we stayed a few extra days. We camped here in a Motorhome.
