Nestled in the upper headwaters of the San Gregorio Creek watershed, El Corte de Madera Creek Preserve transects lush redwood forests, chaparral-dotted hillsides, sandstone boulders, and creeks. Located on Skyline Boulevard in Woodside, the Mid-Peninsula Open Space preserve is a great destination for hiking, biking, and horseback riding. Sempervirens Fund helped grow the preserve to 2,906-acres and 34-miles of trails. The world-famous, 1,800-year old Methuselah Tree can be found here.
