The Mid-Peninsula’s many parks and open space preserves contain a virtually endless network of scenic trails for walking and running. Terrain varies from gentle to steep, with grasslands, oaks and madrone trees at lower elevations and redwoods higher up. Some of the more popular places include Huddart and Wunderlicht Parks, Windy Hill and Purissima Creek Redwoods. Consult the Parks & Preserves listings for details.
