Very quiet and scenic site. We arrived a little after dark and most of the sites were taken. While this site is “free” they ask you to go to the visitors center to pay the park entrance fee. We could hear the buffalo in the field next to the grounds all night. As well as the coyotes howling and yipping all night. We will certainly come back to this site on our next trip west! Be careful setting up after dark as there are prairie dog holes all around you.
I would suggest getting reservations. We stopped on a Friday with out one, they were booked. We only wanted one night in a tent. They don’t have designated tent sites but they have one overflow sight and they let us use it for the night. Price is great, $20 per night. Easy to get rvs into the spots and a lot to do for the kids.
We were the only tent campers here, about half of the 16rv spots were taken. It’s right on a little river and has a play set and portapotty. Self check in and cheap! About 10 min off of I80. It is a great spot to stop for the night.
