Tilden Nature Area is a 740-acre preserve located just North of Tilden Regional Park. With over 10 miles of hiking trails, the preserve contains a blend of native and introduced plant communities, including oak/bay woodlands, grasslands, eucalyptus forests, and streams. Hikes range from the leisurely, self-guided Jewel Lake Nature Trail to a vigorous climb up Wildcat Peak (elevation 1,211′) for panoramic, San Francisco Bay views. A 750-foot boardwalk through the woods leads to Jewel Lake, a historic reservoir and waterworks, and a peaceful place to watch wildlife. At Tilden Nature Area one can also find the renowned Environmental Education Center (EEC), headquarters for the area’s interpretive programs, and the historic Little Farm.
