Long Beach Island — universally called LBI — is an 18-mile barrier island off the southern New Jersey coast, connected to the mainland by a single causeway at Ship Bottom. It is one of the classic Jersey Shore summer destinations, quieter and more family-oriented than the boardwalk towns further north.
The island is narrow enough that you can walk from the bay side to the ocean in a few minutes. Beach Haven at the southern end has the most restaurants, shops, and nightlife. Surf City and Harvey Cedars in the middle are more residential. Barnegat Light at the northern tip is where you will find "Old Barney," the 1859 lighthouse, and some of the best fishing on the island.
LBI fills up fast in summer — house rentals book months in advance, and the causeway backs up on Friday afternoons. But the beaches are wide and clean, the surf is reliable, and the sunsets over Barnegat Bay are hard to beat.
