The Nature Center covers 600 acres within Wellesley Island State Park. We have 9 miles of trails that are open year round and our 3500 square foot Nature Center is full of family friendly exhibits, including live animals. Other attractions at the Nature Center include our butterfly house that is open in July and August. We have programming year round for both children and adults and are happy to design specialized programming to suit the needs of any group. Our annual Autumn Festival is the Saturday of Columbus Day weekend.
