Home to 250 species of bird (including ibises, pelicans, egrets, herons and double-crested cormorants), 10 species of reptile and one romantic lighthouse, the 13 islands in this refuge can only be reached by boat. The islands' interiors are generally closed to the public, but during daylight hours you can access most of the white-sand beaches, which provide great opportunities for both fishing and manatee viewing.
