Cutler Park is a 700-acre state park in Needham, Massachusetts that lies between Route 128/I-95 and the Charles River. It contains the largest remaining freshwater marsh on the middle Charles River, with parts of its major trail running directly through the marsh via boardwalks, and thus over 100 species of birds have been sighted there. At the north end, a trail goes around Kendrick Pond (also called Cutler Pond).
