Little Cayman is the smallest of the three Cayman Islands, both in area and population. It is located in the Caribbean Sea, about 87 miles northeast of Grand Cayman and five miles 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 long and one mile wide.

Most of the island is at sea level. The highest elevation is about 40 feet. Little Cayman is famous for its scuba diving. The most famous dive site areas, Bloody Bay and Jackson's Bight, are both located on the north side of the island, just west of its midpoint. Bloody Bay is consistently ranked as one of the world's top wall dives with the ocean floor, which was proportedly based on a claim made by the late Phillipe Cousteau (citation needed). At its shallowest point in Bloody Bay, the drop-off goes a depth of 18 feet (Three Fathom Wall) to approximately 1000 feet (314m), in what is a near-vertical topology at recreational depths (and a bit beyond).
