If you make the summit a fantastic view awaits. Be aware the road goes down then up to the road about then up again to the summit!…

Still one of the highest points in the Santa Cruz Mountains, even though the military graded and flattened the actual summit to create an Air Force base. The summit was cleaned of hazardous material in 2009, then carefully restored after a lot of community input. It's a lovely place to visit now!

Climbing Mount Umunhum is a tough but rewarding challenge. The road is steep, with sections reaching up to 18% grades, so pace yourself. The views from the top are spectacular, making the hard work worth it. Start early to avoid traffic and the heat, and be prepared for a long, demanding ascent.

The museum is open Friday through Sunday from 12:00 to 4:00 PM, with a suggested $2 donation for admission, and the museum grounds are open daily from 8:00 AM to sunset.

Bald Peak provides great views of Santa Clara Valley, the Diablo Range, and the Santa Cruz Mountains. Hikers and mountain bikers can access the peak via trails like Hidden Springs and Coyote Peak, which offer moderate to steep climbs. Early mornings or late afternoons are best for enjoying cooler temperatures in hot summer months. The trails are well-maintained and scenic.

A good little climb to get your legs warmed up. This trail does get busy though, especially on weekends, so be courteous to your fellow trail users.
