Teatown is a nonprofit nature preserve and environmental education center in the Lower Hudson Valley, with 15 miles of hiking trails, a two-acre island refuge for over 230 species of native wildflowers, year-round programming, wildlife exhibits, and natural science day camps in the summer and school breaks. Our mission is to inspire our community to lifelong environmental stewardship.


Through education, science and stewardship, we aim to preserve the beauty and biodiversity of our landscape and cultivate a community of nature stewards.


We manage a 1,000 acre preserve that includes the 41-acre Teatown Lake, 7-acre Shadow Lake and 9-acre Vernay Lake, streams, waterfalls, hardwood swamps, mixed forests and meadows.


15 miles of hiking trails open daily from dawn to dusk plus the 6.5 Teatown-Kitchawan Trail.  Trails also connect to the Briarcliff Peekskill Trailway and the Croton Aqueduct Trail.


30,000 each year – Including more than 4,000 people attending our Hudson River EagleFest(sm), Pancake Breakfast and Spring PlantFest.  10,000 people hike our trails annually and twice that amount participate in educational programs and events.

20,000+ students participate in environmental education programs throughout the lower Hudson Valley.  Our education efforts include a wide range of classes, lectures and outdoor activities, on and offsite, for children grades K to 12, for families and adults: all focused on nature and the role of stewardship in preserving biodiversity.
