Grand Cayman is one of a group of three magnificent tropical islands Christopher Columbus called "Las Tortugas" (the turtles) for the sea creatures he found in the ocean water. The designation did not endure, however, for on later maps the islands were labeled the Caimanau, the Carib Indian word for "crocodile." The name "Caimanas" refers inaccurately to the iguanas native to the islands, which were perhaps at one point mistaken for crocodiles. Among other attractions, visitors to the island will enjoy learning about the turtles, visiting the town of Hell, exploring Seven-Mile Beach and enjoying the undersea world.
