This is not a very exciting trail to hike. It’s pretty much a trail surrounded by thick walls of vegetation, with almost no opportunity to view your surroundings. The trail is 70% rocks/gravel, and 30% hard packed clay, so avoid wearing snickers

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 Almaden Quicksilver Mining Museum is in the historic 1854 Casa Grande manor. The museum gives visitors a glimpse into the history of mercury (also known as quicksilver) mining and the role it played in the California Gold Rush. Visitors can explore exhibits of 19th-century mining photos, a mine tunnel diorama, and artifacts from mining families. 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.

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.
