This is a world away from the cities yet right in the neighborhood of Danville! The drive up the mountain takes approx 40 mins by car but a lot more on bike. There is a rock cave park on the way approx 20 mins out which is a great place to hike take kids along and picnic. Top of the peak is a nice observation deck that provides surreal views of all across the bay! You can see the city on far end and deep into the Central Valley on the other side.

A must visit place!!
