About Sierra Azul

The Sierra Azul mountain range is located in central California, stretching along the eastern edge of Santa Clara County. This rugged, heavily forested range is characterized by steep, rocky terrain, with numerous canyons, ridges, and peaks rising to elevations over 3,600 meters (12,000 feet). The range is part of the larger Diablo Range, which forms the eastern boundary of the Santa Clara Valley. The landscape is dominated by chaparral and oak-studded slopes, transitioning to coniferous forests at higher elevations. Several creeks and small rivers flow through the range, including the Arroyo Hondo and Llagas Creek.
