The first private community glimpsed at after crossing over the gateway to Hilton Head Island is Windmill Harbour, located immediately on the right and situated along the Intracoastal Waterway, where breathtaking sunsets can be seen in all their splendor. The community's signature is in the harbour's technologically advanced lock system, protecting the 260-slip basin from wakes, currents and silting while affording direct boating access to the Intracoastal Waterway and the Calibogue Sound.

In the heart of Windmill Harbour is the award-winning South Carolina Yacht Club. The clubhouse is perched beside the sheltered waters and architecturally reflects the heritage of Charleston and the Lowcountry, a theme found throughout Windmill Harbour. A waterfront sports center provides excellent recreational facilities as well.
