Gillette Castle State Park

The famed actor and playwright William Hooker Gillette, who was born in Connecticut and lived here in the early 1900s, had a distinctive residence that can be toured as part of a variety of activities at this historic site, including hiking and camping. The 24-room mansion, which is decorated in a Medieval style, has several unique features that Gillette personally planned and had made by regional artists.

Visitors laud the building's remarkable architectural details and the stunning river views from the outside terrace. The neighboring 184-acre property bordering the Connecticut River has a network of short walking routes that meander through it, including one that goes beside an old railroad track and offers wonderful scenery and plenty of spots to picnic.

In the summer, there is a cost for castle visits; however, there is always free access to the park. In the neighboring village of East Haddam, the Boardman House bed & breakfast provides opulent lodging close to the river.
