What's special

BREATHTAKING 180-DEGREE WATER & MARSH VIEWS! Words simply cannot capture the extraordinary long-range views from this beautifully updated Wild Dunes retreat. From the moment you step through the front door, you are greeted by sweeping vistas of Morgan Creek, Dewees Island, the Intracoastal Waterway, the marshes of Mount Pleasant, and nearly to Awendaw. Visible from almost every room in the home, these spectacular views stretch for miles and become truly unforgettable at sunset.Privately situated on one of the most desirable and secluded lots on the outer islands of Wild Dunes, this beautifully maintained four-bedroom, 3.5-bath home offers the perfect combination of privacy, comfort, and quintessential Lowcountry living. Two of the four bedrooms feature en suite baths, creatingwonderful accommodations for family and guests. The home's outdoor living spaces are every bit as impressive as the views. Expansive rear decking spans the entire width of the home, providing multiple areas for relaxing, dining, and entertaining while taking in the remarkable surroundings. A two-level gazebo overlooking the water and marsh includes a hot tub--the perfect place to unwind while watching the sunset. And for those dreaming of their own private resort-style oasis, the current owner has received approvals from the City of Isle of Palms and Wild Dunes to add a swimming pool within the rear decking, should the new owner desire. Additional features include abundant storage, particularly within the spacious lower-level garage area, and the convenience of an elevator providing access to every floor. Despite its incredible sense of privacy and serenity, this special property is located within Wild Dunes Resort, offering convenient access to two world-class golf courses, tennis, exceptional dining, and resort amenities. And when it's time for the beach, simply hop on the golf cart for a short ride to the ocean. Spectacular views. Exceptional privacy. Incredible outdoor living. A premier Wild Dunes location. This is more than a home--it's an opportunity to experience the very best of Lowcountry living from a setting that truly must be seen to be believed.
