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.
