This preserve in the Eastern foothills of Santa Clara County offers sweeping views of the Valley and the opportunity to stroll through diverse landscapes including oak woodlands, rolling grassland, and chaparral communities, characterized by their groups of shrubs. Perched above Alum Rock Park, the area protects watersheds, areas of land that absorb water for it to flow into streams and reservoirs, like Penitencia Creek and is home to several protected wildlife species including the California red-legged frog, California tiger salamander, American badger, and Western burrowing owl and other species such as golden eagle, mountain lion, bobcat, and gray fox.

The Aquila Loop Trail is a mellow hike, perfect for beginners and families with young children. Enjoy expansive views as you stroll through grasslands and rock outcroppings that were once part of the ocean floor. Keep your eyes peeled for red-tailed hawks, bobcats, and acorn woodpeckers.

The preserve offers multi-use trails open to hikers, mountain bikers, and equestrians. Stop at one of four benches along the trails to relax and enjoy the views.

Please note that there is NO access to Sierra Vista from Alum Rock Park through Alum Rock Falls Road. Trespassing is strictly prohibited.
