Welcome to Mt. Madonna County Park, one of the most majestic of Santa Clara County's regional park and recreation areas. This 4,605-acre park is dominated by the redwood forest so characteristic of the Santa Cruz Mountain range. To the east, the park overlooks the Santa Clara Valley, to the west, Monterey Bay. As the slopes of Mt. Madonna descend toward the valley, the landscape changes from redwood forest to oak woodland, dense chaparral and grassy meadows. Park visitors may learn about areas where Ohlone Indians hunted and harvested, and will understand why cattle baron Henry Miller spent his summers here. Enjoy your visit today, and return often to the pristine redwood forest of Mt. Madonna County Park. Mt. Madonna Stables offers horseback trail rides, it is a wonderful way to explore the beauty of this park.

You can follow the path of the Banana Slug, California Newt, Gray Fox, or Mountain Lion! The family friendly California Newt trail is tied to the Agents of Discovery​ activity for mobile devices. There are colored markers at each intersection to help guide hikers along the trails. You can find the start of the hikes uphill from the Visitor Center/Ranger Station near the entrance to the Henry Miller Site.
