Rather get on the water instead of in the water? Now you can see the wonders under the sea without having to put on any scuba or snorkel equipment! This popular excursion invites you to skim over the only living coral barrier reef in North America in a glass bottom catamaran. These “windows to the reef” glass bottom boats provide continuous viewing for all guests. A myriad of tropical fish and other sea life can be found off the coast of Key West, and a glass bottom boat can be your portal.
