During the plovers' nesting season (early April through June), most of the beach is usually closed. July is limited; August through March the beach is open.
Rest rooms are located in parking lots 1 (seasonal) and 4 (year-round) and are wheelchair accessible. Potable water is available only at the lot 1 rest rooms.
Covering about two-thirds of Plum Island, the wildlife refuge is a favorite destination for Boston-area families. The refuge is operated by the U.S. Fish and Wildlife Service; it is one of the very few natural barrier beach, dune, and salt marsh complexes left on the coast of New England. Along with the abundant wildlife on view here in its natural habitat, the great attraction of Plum Island (which is what the locals call it) is the beach.
Those who are in the know arrive at the refuge very early (before 8:30 a.m. on weekends in the summer), since only a few parking spots are available. Several observation towers are well used by bird-watchers in March and April, the peak migration periods for ducks and other waterfowl; the views are always good, though, and there are always birds to see—300 or so species live in the area.
The 6-mile-long beach is nearly always deserted. Because of the strong undertow, it’s not a good place for families with young children; also, there are no lifeguards. At the extreme end is Sandy Point State Reservation (www.massparks.org) and Sandy Point, which is owned by the state of Massachusetts and is a more placid place for a swim.
NOTE: Don’t bring pets; do bring bug spray.
