Need suggestions for camping close to North Carolina shore

Rodanthe NC in the Outer Banks.
I recommend the Hatteras KOA or Camp Hatteras.
AT both campgrounds its a 10 min walk to sound side to see sunsets.
KOA has a pier you can walk out onto that is covered on the end
Camp Hatteras also has sites on sound side.

But both places may round $100 per night in prime season.
There are other campgrounds (some less) but I feel the above 2 are the nicest.
If you prefer the no electric/water campgrounds, the National Park service has 4 down in the Outer Banks.
