Description Little Cayman is the smallest of the three Cayman Islands, a British overseas territories, both in area and population. It is located in the Caribbean Sea, about 87 miles (140 km) northeast of Grand Cayman and five miles (8 km) west of Cayman Brac. Little Cayman has a permanent population of less than 170 and is less than ten square miles in area, about ten miles (16 km) long and one mile (1.6 km) wide. The first recorded sighting of Little Cayman, along with Cayman Brac, was by Christopher Columbus on May 10, 1503 on his fourth and final voyage, when heavy winds forced his ship off course. At that time, he named the islands 'Las Tortugas' for the many sea turtles found living there. The islands were later renamed 'Las Caymanas' for the iguanas that were thought to be caimans living there.
