ECOTOUR:  Our Ecotour will take you through the estuaries of the PARKER RIVER NATIONAL WILDLIFE REFUGE on Plum Island. It is a natural barrier island stretching along the Massachusetts Atlantic coast between the mouth of the Merrimack River to the north and the mouth of the Ipswich River to the south.  The Refuge occupies the southern three-fourths of the island and is 4,662 acres in size. Included within this space are 6.5 miles of sandy beach, approximately 3,000 acres of salt marsh, three managed fresh water impoundments, and one of the few unspoiled dune-beach complexes still existing in the Northeast. You will see many varieties of birds and other marsh life as we travel through the small estuaries and rivers that crisscross this miracle of Nature! Since this trip is contingent upon the tides please call (603-682-2293) and reserve space now.
