Fort George Cay
An uninhabited cay and a protected national park, Fort George Cay was once a fortified island that protected the surrounding waters from pirates. Cannons put in place during the 19th century are underwater here and can be viewed by snorkelers. The beach is stunning, a photographer's delight. The curved shoreline creates swirls of different shades of turquoise in the water; at low tide sandbars appear, and the blue-and-green water looks even brighter. This is a great spot to search for sand dollars, so bring a cookie tin to bring them back home in. You can collect only white sand dollars; gray or dark ones are alive and illegal to take. All the excursion companies make stops here on their full-day trips, so ask if the island is on the itinerary of the boat you plan to take, either for snorkeling or a beach picnic.
