The check in process was excellent and the attendant was very informative. Appreciated the laundry facilities although the price was higher than at Yellowstone for some reason. Our campsite was small and dusty. Enjoyed walking the dogs around the campsites.

Campground is located right between tetons and yellowstone, the perfect spot if you’re trying to see both parks! The cabin was super clean and the campground had everything we needed. I highly recommend!!
