A preserve that blends Santa Clara valley views with remnants from a Jesuit sanctuary and a pistol firing range, St. Joseph's Hill Open Space Preserve is popular with local dogwalkers, runners, and cyclists.  Los Gatos is nestled just north of the preserve, and you can hike into St. Joseph's from that town's Novitiate Park. Lexington Reservoir, a popular fishing spot, sits to the south: the reservoir and southwestern portion of St. Joseph's is managed by Santa Clara County. St. Joseph's western border is CA 17, and traffic noise (especially trucks downshifting for the grade) is a companion on some trails. Directly east (through Lexington County Park) is MROSD's huge and rugged Sierra Azul Open Space Preserve, dominated by 3,486 foot Mount Umunhum. 
     St. Joseph's is small, but features a few short steep trails, and a couple options for loops. All hikes starting at Lexington Reservoir climb on Jones Trail, but once in MROSD territory you can choose 3 loops all around 3 miles. Whatever trails you choose, be sure to wear sturdy footwear, because the trails are rocky.
     For the featured hike, start at Lexington Reservoir, begin walking uphill on Jones Trail, marked by a SJ03 gate. This old, crumbly once-paved road, open to hikers, cyclists, and equestrians, shoots straight uphill, lined with eucalyptus, broom, and sagebrush. The steepest bit is over after 0.15 mile, and the grade tapers off (as well as the pavement) near a MROSD information signboard, where you can check your progress on a map.

I decided to start Reno Motorcycle Riders Group because I wanted to be part of a group of people who enjoyed my passion... I was excited and nervous. Our group has grown by leaps and bounds. I never thought it would be this big.
