Coyote Peak Loop moderate workout
Santa Teresa’s Coyote Peak delivers the 360-degree summit experience tech workers crave without the soul-crushing crowds of Mission Peak. The 3.8-mile loop climbs 750 feet through oak-studded grasslands, offering Mount Hamilton views to the east and ocean glimpses west on clear days.

Mission Peak from Ohlone College
Mission Peak stands as Silicon Valley’s Everest—a brutal 2,100-foot climb that separates casual walkers from serious hikers. The Ohlone College route adds distance but solves the Stanford Avenue parking nightmare with 900 reliable spaces. This strategic choice alone transforms a frustrating experience into a manageable challenge.
The 6.8-mile round trip punishes unprepared legs with relentless switchbacks on shadeless fire roads. Summer temperatures can hit 100°F on the exposed slopes—carry 3 liters minimum. But reaching that famous summit pole, seeing the entire Bay Area spread below, creates an addictive high that keeps people coming back.
Weekends bring continuous crowds marching up the mountain. For solitude, start at sunrise or tackle it on a Tuesday. The college parking costs $4 weekdays but goes free Sundays. Pro move: headlamp for sunset descent avoids both heat and humanity.

Mount Umunhum Trail historic summit
Mount Umunhum offers Silicon Valley’s most meaningful summit experience. At 3,486 feet, this sacred Ohlone site topped by a massive concrete radar cube delivers 360-degree views from the Sierra Nevada to Monterey Bay. The 7.8-mile round trip climbs steadily through oak woodlands and chaparral on a beautifully engineered trail.
Only 23 parking spots at Bald Mountain trailhead fill by 9am weekends—arrive at sunrise or hike weekdays. The summit’s ceremonial circle honors the Amah Mutsun people, while interpretive displays explain both indigenous history and Cold War operations. Pack layers: the peak runs 20 degrees cooler than the valley.
Clever groups drop hikers at Bald Mountain while drivers continue to the summit lot (54 spaces), then everyone meets at the top. Water and restrooms bookend the trail, but the middle miles offer no services. Spring wildflowers and fall colors make ideal seasons.
