Head west on SR 9 from Saratoga, on San Jose's southwestern edge. The road is winding in spots but easy to drive, with pretty views and lots of pullouts along the way. At Castle Rock State Park you can hike through forests of coast redwood, Douglas fir and madrone trees. Farther south there are more old-growth redwoods to explore at Henry Cowell Redwoods State Park.
