What does a vineyard and RV park have in common? Fun, relaxation and a vacation setting you won't soon forget. Here at Grape County RV Park, we are located in the wine capitol of Arkansas. We're proud to offer a unique and varied experience for our visitors. You can spend your nights camping in your RV and enjoy your days exploring the different wineries in the area located just a few minutes from the park.
This is a great place to stop. Not to far off of I-40 and has beautiful surroundings. It is on the wine trail and there are vineyards across the road.
