Eolia Mansion at Harkness Memorial State Park; This is a GREAT place to picnic under the trees or on the greens, walk around the mansion gardens, fly kites, or go down and wade in the water at the beach. People have weddings here, there are contests, and it's just gorgeous scenery at the shore in Waterford, CT.
