A pond of clear water and shimmering coral are draws of Nylon Pool, which Princess Margaret visited on her honeymoon—but these are hardly the only reasons to visit. What makes these shallow bodies of water within the ocean magical is their location in the middle of the Caribbean Sea (the pools are all enclosed by coral, hence the name “pool”). Book one of the glass-bottom boats docked at Pigeon Point and gaze down at local marine life during the fifteen-minute journey over. It’s a little surreal to find mini swimming pools enclosed by dark seawater, but it’s great fun to float and snorkel here. Locals swear that a swim in the aquamarine waters is the secret to eternal youth.
