Exuma Cays Land and Sea Park stretches 22 mi. (35 km) from Wax Cay Cut in the north to Conch Cut in the south and is accessible only by boat. Said to be the first national park of its kind, this marine preserve was established in 1958. The park is made up of 15 major cays and many smaller islands in a pristine area encompassing 176 square miles (456 sq km). The vast underwater park attracts snorkeling and scuba enthusiasts from around the world. The bird and marine life sanctuary is home to sea turtles, rock iguanas and the Bahamas Hutia, a small rodent once thought to be extinct.
