Description: This is a nearly 7,000 acre park with views of the Calaveras Reservoir, the San Antonio Reservoir and Mt. Diablo, Some of the trails run streamside, through meadows, and along the ridge. This park has giant Oaks and interesting geology. I enjoy taking the Canyon View Trail to "Little Yosemite," a gorge with beautiful, small waterfalls, about 2.5 miles there and back. If you're looking for something challenging, the Flag Hill Trail is a 1.3 mile steep trail with views of the park and Calaveras Reservoir. You can hike along the ridge and have the option to take a number of trails back.
