Mount Umunhum, rising 3,486 feet in the Sierra Azul Preserve, offers a stunning wilderness experience in the Santa Cruz Mountains, encompassing over 19,000 acres of diverse landscapes. With 26 miles of multiuse trails, visitors can hike, bike, or horseback ride while enjoying scenic views and the rich natural habitat, home to wildlife such as deer, bobcats, and mountain lions.
This unique preserve blends natural beauty with a rich history, having been inhabited for millennia by Native Americans and later by European settlers, as well as serving as a Cold War radar station. The area has been carefully restored for public access, providing trails and facilities that enhance the exploration of its cultural and natural heritage.
