A Surprise- right next door to West Yellowstone
Yes, it's right on route 191 but it is clean and well managed. Good for a night or two if you need extra time in the area. We needed such a day and stayed in site # 6.
Sites 7, 8 and 9 looked good--- but some back right up to route # 191 with whizzing cars and noise--- not a place to let a dog run loose.
