A rare offering in Carlton Dunes, this exceptional oceanfront penthouse is one of only 14 penthouse residences within this exclusive community adjacent to The Ritz-Carlton, Amelia Island. Positioned on the top floor, this 4-bedroom, 3.5-bath residence is entered by private elevator through a dedicated foyer and framed by sweeping Atlantic Ocean views. Soaring 12-foot ceilings throughout enhance the open floor plan, natural light, and generous living spaces.
