Castle Rock State Park: Saratoga Gap/ Ridge Trail/ Castle Rock Trail Professional Review and Guide
"Castle Rock State Park is on one of the highest ridges in the Santa Cruz Mountains. The hike features great variety: cool, dark mixed forests, creeks and a seasonal waterfall, dry, manzanita-lined ridges, grassy hills, oak savanna, and above all, rock formations. The boulders come in amazing shapes, with curves, crevices, and caves.
On weekends, climbers navigate their way up 90-degree rock faces with chalky fingers. The giant boulder that gives the park its name sits in high woodland toward the end of the hike. There are interpretive exhibits and scenic overlooks along the way."
