Cape henlopen is one of five or six Delaware state parks that offer RV camping. Sites vary in size so make sure you check the details before you book. Using their online campground map along with google earth will give you a pretty good idea. Water and electric hookups only. There are 3 dump stations as you exit the park which is really nice. I have never had to wait. Most sites offer good shade by the local pine trees. Nice bike trails and hiking through the dunes. They even offer free bike rentals. Clean bath houses as well. If they had Full hookups I would give 5 stars (I am spoiled I know).
