We found a little KOA campground called Lyman KOA, in Lyman, Wyoming. We decided to pay to stay. Our laundry basket was calling. lol. The main reason we would pay to stay really :).
This little place wasn’t a bad little place. It wasn’t overly busy and we got a nice shady spot away from other people with water and electricity. Chosing not to have FULL hook up gave us a more private location. We like to be alone. :). In the morning, we would be able to dump our tanks for free. Bonus!
This little campground offered a little store, play area for kids, free showers and washrooms. The price for the campsite was quite reasonable, We believe it was about $35.
Not quite sure how we found this one, may have used RV Parky or for your Android phone RV Parky which is an app you can download for free on your phone. It shows you all kinds of interesting information.
