Love Hatteras KOA. We stayed here for over 15 years in tents, then eventually worked our way up to the cabins. Now that we are RV owners we are able to stay here in our own camper. Good thing because the nightly prices for cabins became WAY overpriced. The RV sites are getting pricey as well. The proximity to the beach is great. There are no roads to cross so the campground is oceanfront. The pool is really nice and my wife and I feel comfortable with the kids riding their bikes all over the facility. There is a cafe onsite serving breakfast and lunch (dinner too I think). Although I typically use my mobile hot spot, Wifi is available. To top it all off Cape Hatteras National Seashore is one of the most beautiful places in the US. I would give 5 stars if it wasn’t so expensive.
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).
