Hallock State Park and Mattituck State Tidal Wetlands

Location: Jamesport & Mattituck, NY

Anchor Site(s): Hallock State Park Preserve and Mattituck State Tidal Wetlands

About the Site: This Stewardship Area is made up of Hallock State Park Preserve and Mattituck State Tidal Wetlands and Waterway Access. Hallock State Park Preserve opened to the public on July 12, 2017. The park preserve sits on 225 acres and has over a mile of beachfront along Long Island Sound and two hiking trails. Hallocks Pond, a four-acre coastal plain pond within the site, was once used for both recreational and agricultural purposes but has now reverted to more natural conditions providing a home to an aquatic community. The New York Natural Heritage Program has identified sixteen ecological communities within the park such as maritime bluffs, coastal woodlands, and small wetlands. The park preserve, once called Jamesport State Park, was renamed Hallock State Park Preserve to reflect the history of the area and the Hallock family, who owned the property for centuries. A visitor’s center for the park is located at the park entrance along Sound Ave. Mattituck State Tidal Wetlands is made up of 60 acres of tidal wetland and creek, 10 acres of shoals and mudflats, with 10 acres of protected park surrounding the inlet. Mattituck Creek is an excellent access site to Long Island Sound, and is a great place for swimming, fishing, and diving.
