First come, first serve. We were right next to the creek. Pull through spot. Vault toilets. No hookups. Small campground. 10 spacious sites. We couldn’t hear anybody at any other site. Felt very comfortable. Cooked over the open fire. Hard sided campers only due to grizzlies. We never saw one there. Did have a buffalo there though. A few miles from the East Entrance of Yellowstone. Worth the beautiful drive.
