Windsurfers and kiteboarders congregate at Anse de Sables Beach in Vieux Fort, at the southeastern tip of St. Lucia, to take advantage of the blue-water and high-wind conditions that the Atlantic Ocean provides. The Reef Kite & Surf Centre (Anse de Sables, Vieux Fort. 758/454-3418) rents equipment and offers lessons from certified instructors in both windsurfing and kiteboarding. A three-hour beginning windsurfing course costs $90, plus $45 to rent equipment for a half day. For kiteboarding, the three-hour starter course costs $125, including equipment. Kiteboarding is particularly strenuous, so participants must be excellent swimmers and in good physical health.
