Valley Stream State Park

Valley Stream State Park is a 97-acre state park located in the village of Valley Stream in Nassau County, New York. The park is one of three state parks located in the Town of Hempstead on Long Island. Like Hempstead Lake State Park, Valley Stream State Park contained Cornell's Pond, a feeder reservoir for the Ridgewood Reservoir.

This park opened in 1928 together with Southern State Parkway, Hempstead Lake State Park, Belmont Lake State Park, and Heckscher State Park. Initially the park included Cornell's Pond, which had a freshwater beach that charged an admission fee of 10 cents. Crowded and unsanitary conditions led local residents to lobby for its closing in 1947.
