7 miles round trip.
From: East entrance of Rockville Hills Park
To: Green Valley Road
The City requires payment of a park entrance fee at the yellow pay station in the parking lot off Rockville Hills—please carry the pass with you whether or not you use the parking lot.
Climb gently through these volcanic rock hills to a remote, grassy valley with a splendid stand of blue oaks. On your descent, you’ll have views of Mt. Diablo, Elkhorn Peak, and the Twin Sisters. Most trees in the park are deciduous, so on a winter day these trails can be comfortably sunny, yet in summer, the predominant blue-oak forest offers welcome shade. This trip begins on a connector trail to the park’s north entrance and then travels wide, unpaved service roads to a paved trail through a private subdivision.
