Discover the spectacular coastline and waters off Nassau above and below sea level on this exciting 1.5-hour adventure. A narrated catamaran cruise around historic Nassau Harbour kicks off the day. Take in the sights as you pass Paradise Island, Blue Lagoon Island, and the dazzling celebrity homes that line the shore. Upon arrival at the underwater marine park, you will transfer to the Seaworld Explorer semi-submarine, where you will sit five feet below the surface in air-conditioned comfort. Cruise to the crystalline waters surrounding Athol Island and observe through the clear viewing panels the colorful colony of coral and rainbow-hued tropical fish that inhabit the "Sea Gardens" as a knowledgeable guide shares information on what you see. Your captain might even throw some food in the water, so be ready with your camera! Glide back to the dock and disembark with plenty of time to enjoy more of Nassau.
