Bay Area Ridge Trail: Sierra Vista Open Space—Lower Calavaras Fault

Dogs Unknown

The Sierra Vista Trail opened in 2011, connecting the Ridge Trail at the lower elevations with the Upper and Lower Calaveras Fault Trail, and creating a long 8.9-mile Ridge Trail segment. This upper Ridge Trail section starts high up on the grassy ridge, with spectacular views of the Santa Clara Valley, and then follows the contours of the steep Alum Rock Canyon before dropping down to Penitencia Creek and climbing out to another ridgetop to the southeast. The end point has sweeping vistas of the valley below and the hills to the east. This is a very exposed trail for much of the route, so start early on hot days.
