Established in 1936 as one of the East Bay Regional Park District's original parks (originally named Round Top Regional Park), Sibley is home to the remains of a 10-million-year-old volcano. The preserve spans 928 acres and features diverse landscapes shaped by volcanic activity and tectonic forces. Visitors can explore several trails that wind through the preserve, each offering a different perspective on the area's natural beauty. The Volcanic Trail, a former quarry haul road, takes you past basalt flows, cinder cones, and lava tubes. Informative brochures available at the visitor center provide insights into the preserve's geological past. The Round Top Loop Trail circles the highest point in the park, offering panoramic views of the Bay Area. The East Bay Skyline National Recreation Trail traverses the preserve along the ridgeline, connecting to other regional parks. Sibley is also home to man-made labyrinths, adding a touch of whimsy to the landscape. The Mazzariello Labyrinth, created in 1989, is a popular spot for reflection and meditation. Keep an eye out for grazing cattle, which help maintain the natural habitat and reduce wildfire risks.
