Joppa Flats (Audubon Society)
Plum Island Turnpike (near Ocean Ave)

Parker River National Wildlife Refuge
Off Plum Island Turnpike, Newbury
Plum Island is a 7 mile long barrier beach. The PRWR extends 7¬†miles and is bordered by the Atlantic Ocean and the Parker River/Plum Island estuaries. It is a birdwatchers delight — an excellent place to observe warblers, shore birds, and water fowl. If you are lucky, you might spot white tail deer, red fox, coyote, skunks, and even an occasional beaver.

Sandy Point State Reservation
Southern tip of Plum Island
It is a bit of a drive (five miles through the PRWR) but well worth the trip. Located on Ipswich Bay, it is an excellent place to watch shore birds or explore tidal pools.

Salisbury State Reservation
Reservation Road (off Route 1a)
Located where the Black Rock Creek flows into the Merrimack River, it is an excellent place for watching or exploring an estuary. During the winter (at low tide) you will see many seals sunning themselves on Badgers Rocks, a few yards off shore in the Merrimack River.
