Tips from the Community

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

Great views from the summit.

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.

An excellent spot to take a break and enjoy the full breath of Lexington Reservoir. There is a Plaque dedicated to deputy Douglas B. Miller, who was fatally wounded while performing his duties.

From the top of the dam you get splendid views out across Lexington Reservoir. To the north you overlook the winding end of the Los Gatos Creek Trail, which connects to the Jones Trail across from the restroom just up the road. The dam itself was constructed in 1952 and stands at nearly 200 feet tall.
