Meet your double-decker glass-bottom boat at Port Lucaya Marina. Board your 60-foot (18-meter) vessel and choose to sit on the sundeck or in a shaded area as you cruise out of the harbor.
As the boat glides down the coast, look out for Cooper's Castle, a fortress perched high on a hill over Freeport. Then turn your attention to the underwater world, clearly visible through the clear glass bottom of the ship.
View the 233-foot (71-meter) Theo's Wreck, a former cargo ship that is now home to underwater plants and plenty of fish. Move on to Brit's Wreck, near Treasure Reef where you're likely to see some sharks.
As you cruise over the calm, tropical waters, listen to your guide's commentary about the marine life, both plant and animal. Watch for queen angelfish, surgeonfish and the colorful blue tang. Relax and enjoy the spectacular underwater views without getting wet. At the conclusion of your 1.5 hour tour, your boat will return to Port Lucaya Marina.
