 Exposed on the steep canyon eastern slopes of the Santa Cruz Mountains, Sanborn County Park has one of the coolest summer climates of Santa Clara County's parks.Towering redwood forests add to this eastern slope exposure in keeping hiking trails comfortable in the heavy use period, from June to September; moreover, there are abundant mixed forest locales having Coast live oak, Pacific madrone, Big leaf maple and Tanbark oak.The park features the first segment of the regional Bay Area Ridge Trail in Santa Clara County, which extends along the ridge of the Santa Cruz Mountains to become the Skyline-to-the-Sea Trail, which continues to the Pacific Ocean.
