Summit Loop is a 9.3 mile loop located just outside of Brisbane, CA and situated in San Bruno Mountain State and County Park.

While there are many access points to the trail, the parking lot at the end of Glen Park Way is a great starting point, although it can be difficult to find available parking during peak hours.

Depending on the time of year, portions of the trail can covered in a dense fog bank, so we’d recommend packing layers and checking the weather ahead of time before setting out on this trail.

Dogs are not allowed inside the park, and since portions of the trail can have a thick underbrush, closed toe shoes and long pants are also recommended.
