Italian for “Beautiful Mountain,” Monte Bello Open Space Preserve is a place of rolling grasslands, dense creekside forests and spectacular vistas. The preserve encompasses the upper Stevens Creek watershed from Monte Bello Ridge to Skyline Ridge. The 3,436-acre preserve is one of Midpen's richest in wildlife and ecosystem diversity.
Monte Bello Preserve is surrounded by other open space preserves and parks, which makes trip options nearly limitless. Black Mountain offers visitors incredible views of Santa Clara Valley and over to the Mt. Hamilton range.
The spine of the Monte Bello Preserve trail system is a popular route among bicyclists. From here, several trails connect to the top of the ridges. This old road descends 400 feet from Page Mill Road through cool forests into the Stevens Creek Canyon.
This self-guided 3-mile loop takes about three hours at a leisurely pace. The first segment, beginning from the main parking area, can accommodate a wide array of physical abilities (although it is not officially designated an easy-access trail). This gently sloping segment of trail, which is at an average grade of 5%, takes visitors to a dramatic vista point and to a bench where visitors can sit and look down Stevens Creek Canyon to see Mt. Umunhum and Loma Prieta, the epicenter of the 1989 earthquake. The route then descends 450 feet into the headwaters of Stevens Creek, continues along the creek, and returns along the San Andreas Fault. Interpretive signs provide insights to the wonders around you. See more.

Activities & Events
Monte Bello Ridge and Black Mountain provide the scenic backdrop to the communities of Palo Alto, Los Altos, Los Altos Hills and Cupertino. Settlers to this area named one of their towns Mountain View because they had a view of Black Mountain. From the top of Black Mountain, visitors have an incredible view of Santa Clara Valley and the Mt. Hamilton Range. On clear days, visitors can see beautiful sunsets from the Black Mountain backpack camp, or watch the fog roll in from the coast. As the fog breaks like a giant wave over the peninsula, one can see why it is often referred to as “waterfog.”
Dairy ranching was prevalent in this area and Monte Bello Ridge was once dotted with cattle. In the late 1800s and early 1900s, this area was the site of several ranches: the Black Mountain Ranch, the Stevens Creek Road Ranch and the Monte Bello Ranch. The Waterwheel Creek Trail follows an old ranch road, where remnants of orchards and vineyards can be seen.
