Oktoberfest Oct 11 from 10AM-5PM
Welcome To The Demarest Nature Center
The Demarest Nature Center is located in Demarest, NJ, USA, and is open to all persons, residents and non-residents alike, every day of the year. In addition to preserving and protecting important open space here in the midst of a large metropolitan area, the center seeks to educate young and old alike as to the beauty of nature and the importance of protecting our environment.
We, the trustees of the Demarest Nature Center Association, encourage you to use this site to find out more about the Demarest Nature Center and its programs. Click on the topic of your choice and find out more. The links will tell you about the Center, introduce you to our events and endeavors, and also take you to other nearby nature centers, as well as environmental organizations, National Parks, and suggestions for things to do. The site is constantly growing and being updated, so we hope you will come back again and again.

Since its incorporation in 1977 the Demarest Nature Center Association has cared for a 55-acre parcel of land bordered by Columbus Road on the west and County Road on the east. The Demarest Nature Center is open to all every day of the year. In addition to protecting woods, vernal ponds, meadows, and a section of the Tenakill Brook, as well as establishing and maintaining walking trails, the center provides educational events for everyone about the beauty of nature and the importance of preserving our amazing forest habitat. Your membership dollars go towards sponsorship of environmental education programs for kindergarten through the fourth grade in the Demarest schools, and a yearly scholarship given to a local high school senior who plans to pursue environment-related studies in college. Your membership also helps support our birdhouse/bird feeder building program, our annual photo contest, maple syrup making, environmental scholarships, monthly community trail walks and the Craft Show at Oktoberfest/Fall Festival Event.
The Demarest Nature Center Association is a 501(c)(3) not-for-profit corporation, run solely by volunteers and receives no funding from the Borough of Demarest.
