The Watershed Center for Environmental Advocacy, Science and Education serves as headquarters for The Watershed Institute’s staff and programs. The Center’s LEED-Platinum certification denotes the highest level of recognition from the U.S. Green Building Council through its Leadership in Energy and Environmental Design program. The building features exhibits and live animal displays and hosts hundreds of educational programs and events each year. The Center is free and is currently open on week days from 9 a.m. – 5 p.m. and weekends from 10 a.m. – 4 p.m.

The Watershed Center is located on the Watershed Reserve in Hopewell Township, Mercer County, N.J., 20 minutes from Princeton, Trenton and New Hope, PA. The Reserve spans nearly 1,000 acres of forest, wetlands, meadows and farmland. More than 10 miles of hiking trails wind through these habitats and pass by two historic farmsteads that date back to the 18th and 19th centuries.

The Watershed Reserve protects a floodplain forest along the Stony Brook with stately sycamore and beech trees. Younger forests are the result of old farm fields gradually transitioning to woods. The Reserve is also home to wildflower meadows, as well as vast rows of organic produce.

We invite you to explore our trails, observe the antics of waterbirds at Wargo Pond and enjoy the wild sights and sounds of nature. Access to our trails is free.
