On our trip to Door County we took our travel trailer to both a state park and Frontier Wilderness campground. Everyone says that the state parks are less crowded, better layout etc. than private parks. We found it to be just the opposite! FWC has HUGE sites (should have brought our cornhole boards) and there is better separation between them than there was at the state park! There are lots of nice playgrounds for the kids, plenty of bathrooms, and very friendly staff. Highly recommend!
