Seaside Park is a large beach and park with convenient parking close to the beach. The park offers many amenities such as cycling/running paths, playgrounds, a splash pad, picnic tables, ball fields, and spacious beach space. Beach sand has a mix of shells and pebbles, with a greater concentration at the shoreline along with small amounts of seaweed. Waves are minimal due to the Long Island Sound, and the slope to the water is gradual.
