Great amenities!
Just outside the west entrance of Yellowstone, the campsite was pretty awesome with the walk in reservation we made. We wanted to snag a campsite inside the park but it was full. We came across a few tent sites just around West Yellowstone, with rain in the forecast and a long tiring drive, we drove past KOA and made a quick u-turn. They had tent availability, free showers and laundry facilities that we desperately needed.
The site itself was close to restrooms and was a small but cute layout, however, the dirt was too soft for gusty winds, we were right under a street lamp and we were so close to the entrance that we could hear all conversations and cars that drove in and out of the park.
The showers and restrooms were nice and clean. A little pricy for what we would usually pay for a no hookup tent site but at the end it gave us exactly what we needed.
