Frelinghuysen Arboretum

In front of the large main house there is the Great Lawn, a large gently sloping manicured grassy expanse in the style of an English county manor landscape; it is the site of outdoor concerts in the warmer months.

There is a Braille Nature Trail in a small wooded hollow just off the Great Lawn which was designed for hands-on exploration.

Garden is worked on by children ages 5–13 during a spring after-school and summer program; the course of study includes cooking and crafts.

The Patriots' Path is a network of hiking, biking, and equestrian trails and green open spaces, and links to other parks in New Jersey.

The arboretum surrounds the Frelinghuysens' Colonial Revival mansion and its formal gardens, and features nature trails with labeled trees and shrubs.
