    Ten Thousand Islands

    The Ten Thousand Islands are a chain of islands and mangrove islets off the coast of southwest Florida, between Cape Romano (at the south end of Marco Island) and the mouth of the Lostmans River. Some of the islands are high spots on a submergent coastline. Others were produced by mangroves growing on oyster bars.
