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.

One of the highest virtually car-free road climbs in the South Bay, Mount Umunhum became quickly one of the most popular biking destinations since opening to the public in 2017 after being closed several decades for military radar operations. The hard work is rewarded with spectacular 360 degree views of the Sierra Azul Open Space Preserve and the surrounding hills, all the way to the Pacific Ocean in the West and the SF Bay to the north. Modern restrooms, drinking water fountains, and viewing terraces with benches welcome the weary. Don't be afraid, or too overwhelmed by your superpowers if you look at komoot's 9800 ft uphill climb estimate for this highlight. Their software is off by a factor of 5x or more. The actual elevation difference is around 1800 feet (about 600 meters). According to GoogleMaps the distance is only 5.2 miles, with about 2000 feet uphill. Even that is not bad, and you deserve to be proud ;-)
