At Stony Brook, an extensive boardwalk system allows you to follow along the edge of Teal Marsh for a great view of turtles, fish, muskrats, and great blue herons. The boardwalk leads to a grove of beech trees right in the middle of Kingfisher Pond, where wood ducks, black ducks, and Canada geese can often be seen. In the summer, keep an eye and ear out for the buzz of activity in the butterfly garden by the nature center.
