This trail was opened to the public on September 18, 2017. The trail starts at the parking lot of Bald Mountain Trail
It climbs steadily (1,200 ft) for 3.7 miles to the summit of Mount Umunhum, one of the highest peaks in the Santa Cruz Mountains. The trail is excellent and easy to follow, making its way up lots of switchbacks to ease the climb.
The trail goes through a variety of trees such as oak, madrone, manzanita etc. The views from the summit are great: Silicon Valley lies below you, and (on a clear day) one can see all the way to San Francisco, Monterey Bay, and the Pacific Ocean. There are great views of all the mountains in the area, including Mount Hamilton and Mount Diablo. There are a few interpretive signs along the trail and many more on the summit area.
History & Background
The summit of Mount Umunhum has an eight story concrete tower that is visible from many places in the south Bay Area. That tower was once a base holding a radar dish operated by the US Air Force from 1957-1980. After the base closed, the land was bought by the Mid Peninsula Open Space District (mid-Pen) to be used as an open space for the public. However, due to hazardous materials and other safety issues, it was not open to the public until September 18, 2017. For over 30 years Mid-Pen worked on returning the area to mostly its original natural environment. However, they kept the iconic 86 foot tower.
The mountain's name means Hummingbird in the Ohlone language.
