Rockingham's new location consists of 27 acres. The mansion has been restored and painted in colors particular to colonial times. The kitchen wing has been rebuilt with materials such as red oak beams that
might have been used in colonial times, and an 18th century kitchen garden has been planted. With the addition of a historic barn, several outbuildings and an orchard, the site will look much like it did when General Washington stayed there.
The site features guided tours of the mansion and a children's museum. Domestic chores such as
open hearth cooking and spinning are demonstrated during special events held in the park, including a celebration of Washington's birthday. Visitors can also enjoy extensive recreational opportunities including hiking, biking, canoeing, kayaking and fishing along the adjoining Delaware and Raritan Canal State Park. Rockingham is listed on the New Jersey and National Registers of Historic Places.
