🏆 Causeway Beach — Scenic beach on the Nahant peninsula connected to Lynn by a dramatic mile-long causeway
Nahant Beach Reservation occupies a dramatic mile-long causeway connecting the Nahant peninsula to the mainland at Lynn. The beach offers swimming on both sides — calmer Lynn Harbor water to the west and open ocean surf to the east. The causeway itself is a remarkable geological feature — a natural tombolo (sand spit) reinforced over centuries. Views from the beach encompass the Boston skyline, the harbor islands, and the open Atlantic.
