We had planned to stay 2 nights at the Snake River RV Park, but it was very crowded and the sites were too close together. We had reservations, but still ended up in an overflow area, with a huge sink hole which we almost backed into. The site was next to the playground, and kids were out till after 10 pm. We left after one night.
Reservations are suggested during the summer season for a shaded and grassy RV site. Playground. Dog area. Cabins too.
