About This Beach
Plum Island Beach offers a unique blend of natural beauty and a relaxed atmosphere. The meeting of the Merrimack River and the Atlantic Ocean creates a dynamic environment with varying water conditions and expansive sandy areas. While facilities are available (though inconsistent), the beach often provides a less crowded experience compared to other nearby beaches, particularly during off-peak times. The stunning sunsets are a major draw.
