The Somerset County Park Commission Environmental Education Center, Lord Stirling Park, is nestled within 425 acres of the western portion of the Great Swamp Basin of the Passaic River in the Basking Ridge section of Bernards Township. The variety of habitats of floodplains, swamps, rivers, intermittent streams, marshes, meadows, and natural and man-made ponds, fields, and forests provide homes for diverse plant and animal populations in this environmentally sensitive park. All are within walking distance of the multi-faceted Education Center building. The Great Swamp Exhibit, a swamp vivarium, and an environmentally based library are located within the Center itself, while trails run through a wildlife sanctuary. Activities include hiking, environmental programs, birdwatching, and cross-country skiing.
