Tips

Looming large over San Francisco and the northern peninsula, the wilderness preserve of San Bruno Mountain State and County park is home to several rare and endangered species of flora, fauna and wildlife, including the elfin butterfly. The San Bruno Mountain Summit Loop and Ridge Trail offers stunning views of the Pacific Ocean, San Francisco and the Central Bay Area as well as numerous wildlife and plant viewing opportunities. San Bruno Mountain can often be windy and covered in clouds and fog so check the weather forecast before heading out if you’re looking to enjoy the views. Paid parking is available inside the State Park entrance off Guadalupe Canyon Parkway. Dogs and pets are not allowed on this route. Once you park, take the Summit Loop Trail to Ridge Trail and follow it as far as it goes. On your way back, take a right back onto the Summit Loop Trail and return to the parking lot. Note: the Summit Loop Trail can be overgrown so best to wear pants and closed-toe shoes on this hike.

Parking area at the end of Radio Rd.

One of the best views you can get of SF, and a favorite trail running spot of mine. **BEWARE** The summit loop trail has quite a bit of poison oak overgrowth, some spots are unavoidable to make small contact at the knee/thigh level, as of 2 weeks ago, so wear pants or take the access road to the cell towers. It's a short portion of the trip, but once you get near the top of the ridge, you're in the clear. Also, it can get windy and foggy at times, so check the weather and have a jacket just incase. Great hike/walk/run.

Windy but beautiful! I’ve explored San Bruno Mountain quite a bit but this was my first time on the Ridge. Awesome views of the Bay and totally worth braving the 30-mph winds!

I am so happy that I live less than a ten min walk from a trail into San Bruno Mountain. I recorded the hike starting from my house, the whole 9.2 mile trail and back. Clocked in 11.85 miles. Loved this hike. The ridge trail has absolutely no shade so i advise to wear a hat and sunscreen.

Excellent trail to view the San Francisco skyline and Bay. Beautiful views of the ocean too. Not too difficult of a trail either! We got lucky and had a cloudless/fogless day; it truly made the hike worthwhile. The wind can get a bit ridiculous though. Tie a hat to your head!

Half of the big left loop is overgrown with probable poison oak in the area.....pants are necessary. It’s a cool area though, I would probably avoid that circular loop and stick to the more popular trails there.

Trail is narrow and overgrown with thorns and poison oak for most of the hike

Nice challenge and lots of views but very windy on the ridge trail. The summit loop trail was great—not too windy and pretty. I’ll come back for the loop trail but probably won’t do this route again.

Great longer hike that's still close to the city. Beautiful views of San Francisco and the water along with wildflowers.
