Wonderful park. We stayed for the month of June and had a beautiful Yellowstone River-front spot. Everything was immaculate and well maintained. The park managers were lovely people. The only downside (which was minor) is that there was considerable road noise. However, this dies down at night.
Our nightly rate did not include electricity and was an off-season monthly deal. Wonderful park, wonderful people. Immaculately clean. Cleaning staff was mainly work campers, and all were exceptional. Next to beautiful green area with mowed paths and lots of area to play with grandkids and dogs.
