Killingworth

Killingworth, in Middlesex County, stretches 36 square miles and serves as the quiet crossroads among the Connecticut River, Long Island Sound and the I-91 corridor.

Killingworth is home to Chatfield Hollow State Park, a haven for outdoor enthusiasts with its soft pine woods, jagged ledges and flowing, pristine waters, and a popular spot for hiking, pond and stream fishing, swimming and picnicking. The school system is part of Regional School District #17. The Estuary Transit District provides residents with public transportation, and also connects riders with the Old Saybrook Train Station, which is serviced by the Shoreline East and Amtrak railroads. The largest Christmas tree in the history of Rockefeller Center, a Norway spruce reaching 100 feet in height, had its roots in Killingworth.
