This is our first time at the park and we love it! I would highly recommend staying on the west rim. You are really packed in on the east rim and it’s just off the entrance to the overlook so there’s a lot of activity throughout the day. The sites at the west rim are a little spread out so you will have some privacy. We stayed at site #8 and it was perfect. There’s one site to the right, site #9 and nothing but trees to the left. It’s not close to the bathroom so do not wait until the last minute if you have to go lol. Cheers!
