Nice RV Park
Nice campground near Casper, WY. We just stayed for one night and they were able to accommodate us arriving late with us calling ahead. There is a grassy area by the river that is nice to walk your dog. Shower and bathroom area was clean. There is a little playground for kids.
The only cons was it is close to the train which was a noisy when it came by, but didn’t prevent us from sleeping. Full hook ups, pet friendly.
