Ambergris Cays are located in the sparsely populated southeastern quadrant of the Caicos Bank. They were named after the deposits of ambergris, a waxy secretion that wash ashore from migrating humpback whales.
Greater Ambergris is four miles long by one mile wide and 1,100 acres in total. It was uninhabited until 1999 when private investors developed the exclusive Turks & Caicos Sporting Club and now is a private sanctuary for the owners of the casually luxurious villas dotting the north shore.
Little Ambergris is nearby, only a few hundred yards in very shallow water.
