Stayed at the RV park when visiting Monument Valley in May. The campground is with 5 miles of the MV entrance. Clean restrooms and great sights. Even a few hiking trails off the back of their property, They also provide complimentary transportation to their grocery store, John Wayne Movie theater, Restaurant and Museum/souvenir shop. Sights were level with water elec and sewer. Large washeteria and basic sundry shop on location. It is also a great location for visiting Mexican Hat, Gooseneck Turn and other regional attractions.
We visited Memorial Day Weekend. The campground was empty because it was HOT. The campground is a basic dirt field with only a few small trees. We took the site that had trees for shade. Each site had a picnic table and fire pit. The campground has a cute history and fun touristy things to check out… and it's convenience to Monument Valley is superb. Although the views from our site were less than desirable, the rest of the campground offered picturesque scenes of the nearby "monuments."
If you get to the campgrounds early enough you can set up a tent at the edge. This way you will have a clear view of Monument Valley with no other tents or distractions in the way. Restrooms are clean and close by, so you can walk to them from the campsite. However, it was a little noisy at night because you're camping near the parking lot and some people come late in the evening to set up.
Monument Valley is spectacular! We were fortunate to stay overnight during a full moon and all I can say is do it if you get a chance. The site is clean, well laid out, super easy access from site to several trailheads. Lots of dog friendly folks and great adventure! A little far from the Welcome Center to walk but an easy drive
