High above the banks of the Connecticut River, actor William Gillette (known for portraying Sherlock Holmes) built this quirky fieldstone fortress as a 24-room home with handcrafted locks and spy mirrors. Now a state park, it boasts great picnicking, hiking, and overnight camping. Voted Best State Park.
