Key West or Out West

We've been to the Outer Banks numerous times, but never with the RV. There are numerous options on what to do if your family likes the water, fishing, water sports, etc. Even a great kite ship (Kligs) near Jockey's Ridge in Nags Head - its the biggest natural sand dune in the world! Get an awesome kite at Kligs and climb the dune to use it! You'll find out why the Wright Brothers picked here to experiment with flying! Interesting things to see as well - several great lighthouses to visit, (Hatteras is the most well known, but several others) Kitty Hawk and the Wright Brothers' Museum (If you go there, make it a point to visit this!) and so many really great places to eat - most of them affordable! We love Mama Kwan's, The Black Pelican, Blue Moon (gets really crowded fast!), Red Drum, and for breakfast, Sam & Omie's! All of these places are within a dozen or so miles of Nags Head. If you're adventurous and particularly if you have a 4 wheel drive vehicle, you can go north to Corolla and drive on the beach for miles - there are houses up there! Just be certain to let some air out of your tires and be alert for really soft sand - costs a fortune to be towed out!!
South of Hatteras is Avon and Frisco - beautiful wind-swept area. There's a ferry across to Ocracoke but I know it was severely damaged during one recent storm. Might need to check if it's open for operation. That could be a good day trip for the family.
OBX is a great place to just relax as well. Just one thing to remember - it is ALWAYS WINDY in OBX! Whatever you decide to do, might want to check out https://www.campgroundreviews.com for information from other RVers about campgrounds in the areas you wish to visit. I have used this site for years and have found it to be very useful. Enjoy, be safe, and create many great 'forever' memories!
