Serving as a scenic backdrop to the town of Los Gatos, St. Joseph's Hill Open Space Preserve protects 273-acres of open space land on top of the 1,250-foot hill from which it takes its name. Providing a quick escape from nearby urban areas of the southern peninsula, the historic property begins about a mile from Los Gatos's popular downtown business district. Entered from the north through Los Gatos's Novitiate Park or from the south through Santa Clara County Parks' Lexington Reservoir County Park, the preserve is open for hiking and dog walking, as well as biking and horseback riding on designated trails.
Steep trails wind through grassland, chaparral and oak woodland habitats and offer panoramic views of Santa Clara Valley, Lexington Reservoir and Sierra Azul Preserve. The land still reveals some of its former uses. In 1888, Jesuits founded a school - called a novitiate - and a winery on the hill (observant visitors may notice remnants of abandoned vineyards on the upper slopes). Much of Jones Trail follows the historic alignment of Jones Road, the stage coach route that connected Los Gatos to the small towns of Lexington and Alma, which now lie at the bottom of the Lexington Reservoir.
Midpen and the town of Los Gatos jointly purchased St. Joseph’s Hill Preserve in 1982.
The Jones Trail connects St. Joseph’s Hill Preserve to Novitiate Park on one end, and to Santa Clara County's Lexington Reservoir County Park on the other. This 2.2-mile trail also connects the preserve to the town of Los Gatos, through trail connections with the Flume Trail and the Los Gatos Trail.
A portion of the Jones Trail follows the historic alignment of Jones Road, which was used in the last century by stagecoaches and pack teams.
This 1.5-mile long trail will take you to the summit of St. Joseph's Hill, where you can sit on a bench and take in views of the Lexington Reservoir. To reach this trail, take the Jones Trail from one of the parking areas to the Novitiate Trail. From there, continue on the Novitiate Trail for 0.5 miles until you reach the Manzanita Trail.
This trail features outcroppings of serpentine rock, which lend a greenish color to the sides of the trail at certain points.
