Flat Rock Brook Nature Center is a 150-acre preserve and environmental education center situated on the western slope of the Palisades in Englewood, New Jersey. The Center was established in 1974 by citizens who were deeply committed to land conservation and environmental education.

Comprised of 75 acres of Green Lands owned by the City of Englewood, plus an adjacent 75 acres formerly known as Allison Woods Park, this natural woodland is one of the last remnants of the magnificent Palisades Forest.The preserve is managed by the Flat Rock Brook Nature Association, a non-profit membership supported organization committed to land conservation and environmental education.

A network of self-guiding trails leads to a cascading stream, wetlands, ponds, wildflower meadows, quarry cliffs and woodland. The diversity of the natural landscape allows our members to observe a remarkable array of birds and other wildlife in their natural habitats.

The Flat Rock Brook trails and picnic area are open free to the public every day from dawn to dusk. Visitors are requested to respect the land and its natural residents, to take away only memories, and to leave behind only faint footprints.
