This is a great place to stay for Yellowstone! We stayed in the building with rooms on the backside lower floor facing towards the river and the mountains. If you can book one of these rooms, do it. The view is amazing and the sound of the river is so relaxing. The room was clean and had plenty of room. There are great amenities here such as a pool, hot tub, game room, free s’mores, filtered water machine, free laundry room. Gardiner is a neat town right by the Roosevelt arch entrance close to Mammoth. Highly recommend!
