We went during spring break in mid-March and it was first come first serve, which wasn’t a problem since it wasn’t their main season yet. They had just received 3-feet of snow the week before, so the upper loop was closed off and many of the sites were either completely or partially covered in snow. We found one that had enough room, but the snowmelt had caused most of it to be muddy. The campground has a fire pit and a table. There are also water spickets throughout the campground that are for public use. The camp is within walking distance of the rim and ampitheater as well
I visited here during mid-March and it was a great campground. It was close to the shuttle and the park entrance. Because it is first come first serve you, and since it was Spring break we had to get there around 5 AM to get a good place in line (we ended up 6th in line). Each site has a lot of space with a fire pit and a table. It has trees scattered around but you can still see sky well if you are wanting to stargaze. The only problem we had with it was that we weren’t allowed to hammock on the trees in between each site because it would harm the two foot strip of grass that was there. It just seemed kind of hypocritical considering there are paved asphalt roads throughout. We were able to bypass it by hooking it to a tree and the racks on my truck.
