Hiking is the most popular activity in the park. The main starting points are from the park's entrance, trailhead parking area and from the mountain's summit. Various neighborhood access points including Crocker Road and Carter Street also provide good starting points. Views afforded from many spots on the trails are unparalleled in the Bay Area.
Sightseeing is also popular. Radio Road, leading up from the main entrance, offers visitors the opportunity to drive to the summit of the Mountain and enjoy breathtaking views north to Mt. Tamalpais, east of Mt. Diablo and west to the Farallon Islands.

San Bruno Mountain Day Use Area
In May 2026, new drop-in family picnic sites, restroom, and an interpretive area opened in the grass area near the main parking lot. Six of the park’s nine new picnic sites are fully accessible to people of all abilities. Picnic sites feature new BBQ grills and tables and are configured in groupings of 1, 2 or 4 tables.
Interpretive displays and an exhibit and gathering space are located nearby. All sites are connected by paved pathway that circles the large grassy area, which is a popular spot for volleyball, frisbees, kite-flying, and other recreational activities.
All picnic sites are available on a first come, first served basis.
