From its 30-acre lake and pristine meadows to the gun bunkers, this park operates as an informative exploration area and a fully functioning conference center. The park also includes beach camping, a marine science center, a boat launch and Blackberries Restaurant. A separate cafeteria hosts up to 400 diners, and inexpensive lodgings are available. With summer music events, four different museums and acres of trails, this park gets crowded on summer weekends. Make reservations well in advance if you plan to stay overnight.
