Petit Bois Island (pronounced “petty boy”) is the easternmost of the barrier islands. Its extensive tern colonies are regularly monitored by park rangers. “Sand Island”, located just to the west of Petit Bois, is a dredge spoil island, created as part of the maintenance of the navigation channel to the east and as a means to allow sand to migrate onto and maintain sand levels on Petit Bois. It has very extensive tern colonies that are subject to the same protection as is Petit Bois. Click here for complete information including maps, trails, lagoons, and passes.


All of the barrier islands can only be reached by boat. Click on the boat icon to the right for more information on charter services.  If you are using a personal boat, the GPS way-point provided is for an area that is open to the public and easy to access.
