The trails in the private area, still in use by the Rockefeller family[3] and also open to the public, connect with those in the state park.[4] Many of these trails were planned and laid out by John D. Rockefeller (Sr.) and his descendants.[5] Access to these trails, and additional access to the state park trails, is available from Sleepy Hollow Road and Bedford Road/Route 448 in Sleepy Hollow. A section of the State Park is west of the Preserve, along the Hudson River, and is called the Rockwood Hall section.
