The Great Dunes Beach Deck (Large Pavilion) is located at Great Dunes Beach Park on Beachview Drive just north of the Convention Center. Directions: As you are coming onto Jekyll Island from the Downing-Musgrove Causeway, continue straight until you get to the traffic circle. In the traffic circle, take the 3rd exit (the equivalent of a left turn), which will put you on Beachview Drive heading north. Almost immediately after exiting the traffic circle you will pass the Convention Center entrance which has an electronic sign. Directly north of the Convention Center you will see signs on your right for Great Dunes Beach Park. Turn right into the parking lot and look for the large open-air pavilion next to a set of bathrooms.
