Thanks for all the replies we think we have narrowed it down to staying in Canyon Campground in Yellowstone for 5 nights and then moving on to Tetons for 4 nights we are thinking about staying at Colter Bay trying to decide between the Rv park with full hookups or the basic campground at Colter. The basic campground had better reviews on scenery and campsites but they do not take reservations. Coming from Kansas City that worries me not having reservations does anyone have any thoughts on this campground and it's availability for July since this is a very busy time.
