First evening came it as it got dark. Pretty easy to navigate the site by moonlight and get set up. However, Bison roam through the area and aside from hoofprints they will leave reminders of their presence. There is plenty of room between campsites/ neighbors and during our stay all visitors were pleasant, and courteous. Our first night encounter was hearing what may have been a mountain lion and purred what seemed to be right next to our tent. During the night it had bedded down in our vicinity and had moved on by morning. 2nd night you could hear the bison moving around the campsites. Easy access to trails for hikes. Beautiful skies and amazing views throughout the canyon.
