The Barnegat Peninsula, also known as the Island Beach Peninsula or Barnegat Bay Island and colloquially as "the barrier island", is a 20-mile (32 km) long, narrow barrier peninsula located on the Jersey Shore in Ocean County, New Jersey, United States, that divides the Barnegat Bay from the Atlantic Ocean. It is a vacation destination and summer colony area and is heavily dependent on tourism, real estate and fishing.
Notable communities on the peninsula include Point Pleasant Beach, Bay Head, Mantoloking, Lavallette, Toms River sections of Ortley Beach and Normandy Beach, Seaside Heights, Seaside Park, Brick Township (Beaches I, II, and III), and Berkeley Township. The southern 10 miles (16 km) of the barrier island are preserved in their natural state as Island Beach State Park, New Jersey's longest stretch of undeveloped coastline.[1]
