"This trail has one of the nicest views of the nearby hills and SF Bay. Best time for views from the trail is early Spring or Fall when there is less chance of summer fog over the bay."

Along the crest of the Santa Cruz Mountains, Castle Rock State Park embraces coast redwood, Douglas-fir, and madrone forest, most of which has been left in its wild, natural state. Steep canyons are sprinkled with unusual rock formations that are popular with rock climbers. The forest here is lush and mossy, crisscrossed by 32 miles of hiking and horseback riding trails.

The San Francisco Bay Area is over 7,000 square miles (land mass) and home to more than 7 million people.   The Bay Area  includes nine counties that touch San Francisco Bay: - In the North: Marin, Napa, Solano and Sonoma - In the East: Alameda and Contra Costa - In the South: Santa Clara - On the Peninsula: San Francisco and San Mateo   According to 511.

At the eastern fringe of the San Francisco Bay Region, Mount Diablo, elevation 3,849 feet, stands alone on the edge of California’s great Central Valley. At this point, the Coast Range consists only of low hills, none high enough to block the view from the upper slopes of the mountain. As a result, the view is spectacular. Many visitors to Mount Diablo head straight for the summit to enjoy the famous view.
