Site 609 was perfect for our truck camper. It’s nice to have full hook ups in the national park. It’s just a short walk to Flagg Ranch where there is a little store, gift shop and restaurant. We did go horseback riding here and it was really good! The shower house is great but they could use one more hook to hang your clothes on.

We stayed in a camping cabin. It was incredibly clean and very comfortable. Besides the bunk bed there was a table, chair and dresser. Plus, a lantern. The door had a keyed lock and deadbolt and the windows had screens on them.

Flagg Ranch campground is a beautiful, quiet place between the two national parks that gives you quick easy access to both. We were booked in for one night, but got to stay two additional nights because of cancellations. The staff was very friendly and helpful, the adjacent store and restaurant were close and clean. The bathrooms were clean and spacious. In spite of the primitive nature of our campsite, we had a very good time and thoroughly enjoyed watching the stars at night. We are already planning to stay there again next time we go camping.

Close to the entrance of Yellowstone. Much of the trees weren’t burnt so the view was not nice. Our bathroom smelled really bad and had No hot water for showers in the morning.
