Wadleigh State Park is a small public recreation area on Kezar Lake in Sutton, New Hampshire, used for swimming, picnicking, fishing, and boating, with a bathhouse and playing fields. The park was created after the Village Improvement Society raised money by public subscription to buy the land and gave it to the state. Its early development was carried out by the State Emergency Work Agency and the Civilian Conservation Corps. Soon afterward, the 1938 Hurricane devastated much of the park, destroying new structures and large areas of forest. It also forms part of the 75-mile Sunapee-Ragged-Kearsarge Greenway.
