Mission Peak, Summit and mountain peak in Fremont, California, US

Mission Peak is a summit in the Diablo Range reaching about 2,520 feet, with expansive views across the San Francisco Bay Area and Silicon Valley from its top. Multiple trails from different starting points wind up to this ridge location, passing through open grassland and chaparral vegetation.

Mission Peak lies in Mission Peak Regional Preserve, a park run by the East Bay Regional Park District. On December 27, 1990, sculptor and park ranger Leonard Page and a crew of six erected the "Mission Peeker" pole at the summit, over six feet tall on a foundation two feet deep with 120 pounds of concrete. Vandals sawed it off on September 2, 2023; park crews retrieved, repaired and welded it back on October 4, 2023.

The mountain is a defining landmark for Fremont, appearing on the city's official seal and representing local pride. Visitors gather at the Mission Peeker pole marker to photograph themselves at the summit, making it a focal point for the community.

This location is accessible from multiple parking areas, including Stanford Avenue, Ohlone College, and Sunol Regional Wilderness, though some require permits. Arriving early is advisable since trailheads fill quickly on good weather days, and sturdy hiking boots are recommended for the steep terrain.
