This is a great park with expansive trails that connect to the Almaden Quicksilver Park and the Lexington Reservoir Trails, including St. Joseph's Hill Open Space Preserve. The trails have great vistas and many parts are shaded. The Sierra Azul Open Space Preserve is the district's largest preserve, encompassing 18,831 acres. This park property is a bit of a jigsaw puzzle as the plots of land that were purchased are not contiguous, but the trails are long and it is possible to travel all the way to Lexington Reservoir. The park includes some of the great vista points in the south bay, including Mt. Umunhum (closed to the public), Bald Mountain (2,387 ft), Mount El Sombroso (2,999 ft). The trails are well groomed and marked and many parts are shaded.
Very peaceful. Lots of trees and great views across San Jose. No benches. A word of warning, in the small car park at the hicks road/mount Umunhum road, there have been lots of car break-ins. I was there in November and all but mine of the 6 cars had been broken in to.
This is a nice trail with lots of shaded areas and interesting geological variety!
