The main route east out of Kingston, Windward Road, follows the coastline. It scythes through an industrial zone of oil tanks and a cement works that towers over the ruined defensive bastion of Fort Rock - now the Rockfort Mineral Baths , where you can take a therapeutic soak for J$700. A mile or so further on, turning right at the roundabout takes you on to the Palisadoes , a narrow ten-mile spit of land that leads out past the international airport to the ancient city of Port Royal , from where it's a short hop to the tiny island of Lime Cay .
