Welcome to Tenafly Nature Center The Tenafly Nature Center is a non-profit member-supported nature preserve. Our mission is to protect almost 400 wooded acres, all of its inhabitants and teach the next generations to do the same. Since 1961, TNC has nurtured an appreciation for nature, been a leader in open-space preservation and in environmental education for our community in Tenafly, Bergen County, and beyond. When trails are open we welcome visitors to hike, bird-watch, observe wildlife, cross-country ski, snow-shoe and ice skate on Pfisters Pond. Tenafly Nature Center is a sanctuary for human visitors - an island of green where bonds with nature can be renewed. Whether you have an hour or a day, our woods offer a peaceful respite from the rush of daily life.
