Climb gently through volcanic hills to a remote, grassy valley with a splendid stand of blue oaks. Then ascend to a plateau with views of Mount Diablo, Elkhorn Peak, and the Twin Sisters. The trail then drops into and through a residential subdivision. <br><br>This trip begins on a connector trail to the park's north entrance and then travels paved and unpaved service roads to a paved trail through the subdivision. Most trees in the park are deciduous, so on a winter day the trails can be comfortably sunny, yet in summer the blue-oak forest offers welcome shade.
