The seven hundred acres known as Cutler Park comprise the largest remaining fresh water marsh on the middle Charles. Located in Needham and Dedham, the marsh and small lake attract over 100 species of birds which make Cutler Park a prime spot for nature study. This is a moderate walk on dirt and root covered trails. There are a few options for the pups to cool off in the water. For GPS use 70 Kendrick St, Needham, MA 02494.
