Connecticut’s Largest Island is in Lyme

Selden Island on the east side of the Connecticut River was created in 1854 by storm runoff that separated it from mainland Lyme. At 604 acres, it is the largest Connecticut island. Once a farm and later a stone quarry that produced red granite schist for paving, today it contains Selden Neck State Park which is only accessible by boat — as the state’s sole island state park.
