Embark upon an underwater adventure that takes you through the coral gardens of Water Bay in the Nautilus Semi-Submarine and then explore Coral World Ocean Park.

As we explore the sea grass beds, look for pirate wrecks and try to spot sea turtles and stingrays through your personal viewing window 8 feet beneath the surface. You'll see a myriad of colorful fish as a diver conducts a fish feeding. The underwater naturalist will entertain you with sea stories and some fun historical lore. The Nautilus is a great family activity.

After your cruise, you are free to explore Coral World Ocean Park at your leisure or visit the adjacent Coki Beach for a swim. Visit exhibits that allow you to view animal behaviors hard to see in the wild. Check out the juvenile sharks at the Shark Shallows. Touch a sea star or sea cucumber at the touch pool.

Shop at one of the unique gift shops and have refreshment at the Shark Bar. Enjoy the scenic drive back to the ship.
