An incredibly immersive site with well-kept amenities.
Easily one of the most exciting and wonderful sites I've stayed at. Although I had to cut my visit short (combination of uncooperative dog and being underprepared for the weather), I genuinely enjoyed my time at this site and would strongly recommend it to anyone seeking to immerse themselves in such a striking and beautiful environment.
The distance from the parking area to the campsites - even 65, which I believe is the farthest away - is a short walk on level terrain. It was no problem for me to make a few quick trips to the car to grab my supplies.
Each site has a lovely little shelter area with a picnic table, a fire pit, and a grill. My shelter had a number of screws and nails left by previous campers and served as an excellent place to hang a trash bag, a lantern, and my clothesline. Perhaps the only complaint I had about 65 was trying to figure out which section of flattened ground was designated for my use and which belonged to site 64.
As for the area, it's a short walk to the composting toilets (a pair, designated male/female). Each toilet has a boot scraper out front, hand sanitizer and toilet paper inside, and enough standing room to comfortably bring a dog or young child into the bathroom should you need to keep an eye on them.
At least in 65, there's a decent amount of space between the nearby 63 and 64 campsites, although they are within line of sight if that bothers you. Only one other group was camping at this area at the time I was there, and while I could occasionally hear their chatter, it was unobtrusive and actually kind of reassuring to hear other people in the vicinity.
All sorts of wildlife roam free across the entire park, and this area is no exception. It is surreal and awe inspiring to watch the Bison wander through the sites in this area as they migrate through the park, and I also observed deer and a coyote during my stay.
All in all, this was a great park and an excellent campsite, and I hope to come back when I'm better prepared and I teach my dog to stop challenging Bison.
