The Bay Area tourist may be surprised to learn that volcanoes once roared in the Oakland Hills. This preserve, maintained by the East Bay Park and Recreation Department, features the Round Top, a peak made of 10-million-year-old lava and volcanic debris that is one of the highest points in the Oakland Hills. A visitor center at the park shelves self-guided tour brochures so guests can stroll the park and learn of its historic significance at their own leisure. The hike starts just west of here and follows the Round Top Loop.
