Frelinghuysen Arboretum

Frelinghuysen Arboretum is a 127 acres arboretum which is open daily without charge. The arboretum features thematic collections of plant life, including ornamental grasses, spring-blooming shrubs and perennials, summer shrubs and cutbacks, fall fruit and foliage, shade trees, and a garden called the "promising plants garden" which has underused plants supplied by nurseries, growers, and breeders. 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 are different nature and horse trails. There is a Braille Nature Trail in a small wooded hollow just off the Great Lawn which was designed for hands-on exploration. The Kathryn A. Porter "Branching Out!" 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. Participants grow vegetables, herbs, and flowers to take home. The Patriots' Path is a network of hiking, biking, and equestrian trails and green open spaces, and links to other parks in New Jersey.
