San Bruno Mountain Summit

Located just south of San Francisco, San Bruno Mountain is a great destination for urban dwellers looking for nature close to home. San Bruno Mountain is a favorite spot for wildflower viewing in the Spring and a year-round hiking option. Starting at Daly City BART, this hike takes a neighborhood route to the park, climbs to the mountain’s summit and back down again via a loop trail, and ends at Balboa Park BART.

Places visited: San Bruno Mountain State and County Park
Approximate length: 9 miles
Hiking time: 4-5 hours
Map: San Bruno Mountain Park (PDF)
Terrain: Mix of flat sections and gradual climbing on paved and dirt trails.
Transit schedule: BART
Start point: Daly City BART
End point: Balboa Park BART

Getting to the starting point:

  • From San Francisco, take BART to Daly City.
  • From the Peninsula and South Bay, take Caltrain to Millbrae station. Transfer to BART, and get off at Daly City.
  • From the East Bay, take BART to Daly City.
  • From the North Bay, take Golden Gate Transit Route 70/80 or 10 to San Francisco. Get off at Hyde and Grove streets (just before Market Street), and walk to the Civic Center BART station on Market Street. Take BART to Daly City.


  • A number of variations on this hike are possible. From the mountain’s summit, you can hike out and back along the ridge a ways (note that the Ridge Trail does not connect to neighborhoods in Brisbane, so you will need to return the way you came). For a shorter and less steep hike, take the Saddle Loop Trail from the Old Guadalupe Trail. Or, take the Dairy Ravine and/or Eucalyptus trails with the Summit Loop Trail for a short loop hike.
  • This hike is pleasant even after heavy rains. The muddiest section is a very short section from the small parking lot at the start of the loop. An alternative to this section is to walk along Radio Road  and then turn right to connect to the Summit Loop. Despite its name, the Bog Trail should be passable after wet weather, but feel free to take the paved Old Guadalupe Trail both ways if this is not the case.
  • Be prepared for foggy and/or windy weather at San Bruno Mountain, especially during the summer.
  • Food options are available on Mission Street near the end of the hike. There are several good spots in the park to stop and eat a bag lunch.
