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!…

A scenic stop just off the winding roads of the Santa Cruz Mountains, Lexington Reservoir County Park is a great spot to catch your breath and enjoy the view. The smooth pavement along Alma Bridge Road makes it a popular stretch for cyclists, with rolling terrain and minimal traffic. There's parking, restrooms, and shaded areas if you need a break. From here, you can loop toward Los Gatos or push deeper into the climbs of Highway 17 and Old Santa Cruz Highway.

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.

The Mount Umunhum Trailhead offers some amenities, including bathrooms at both the start and summit. With parking available for about 20 cars, this trail provides great views and is a great spot for sunsets. Aim to hike early in the morning or in the evening as it can get very hot in the summer.
