Crane Beach and all of Castle Neck are protected by the Trustees of Reservations. Pitch pine and scrub oak rise from the masses of marsh grass, sage green hudsonia and dune lichen lining the trails that wind through the dunes.
The 35-mile Ipswich River flows into the Atlantic Ocean at Ipswich Bay. The Ipswich River Water Association works to protect the river and its watershed. Foote Brothers Canoes on Topsfield Rd provides rentals and shuttle service from April to October.
