Welcome to

Stony Kill Farm

Stony Kill Farm Environmental Education Center is located on Route 9D in Wappingers Falls, NY. The 750-acre farm, on the ancestral land of the Wappinger, is the former homesite of the Verplanck Family and is owned today by the NYS Department of Environmental Conservation (DEC) and operated by Stony Kill Foundation.


On July 23rd, 1942 James DeLancey Verplanck and his half-brother John Bayard Verplanck gave 754 acres of land that “shall be forever dedicated to and used exclusively for agricultural purposes” to the NYS Department of Education to be used as a teaching farm by SUNY Farmingdale.  In 1973, the farm and land were transferred to NYS Department of Environmental Conservation.

Stony Kill Foundation, chartered in 1977, is a not-for-profit 501(c)(3) organization originally formed as a friends group to support the work of DEC.  In 2010 the Foundation entered an agreement with the DEC to manage the daily operations of the facility.  Today, the historic grounds continue as a working farm and is home to numerous livestock including cows, sheep, chickens, turkeys and pigs.  The property is open to the public daily, however the barn is open only during Open Barn hours.

The farm was added to the National Register of Historic places in 1980.
