Description

The Summit Loop Trail starts and ends at the trailhead parking lot, which is located on the southeast side of Guadalupe Canyon Parkway, and can only be reached by car from the main park entrance.

From the trailhead, it is recommended that you begin by heading west along April Brook where you'll enjoy diverse riparian plant communities and cross three different foot bridges.

After the last bridge crossing, you'll start to climb up Bitter Cherry Ridge into savannah grasslands dotted with wildflowers and coastal scrub. From this point on, you'll be rewarded by stunning views of the Pacific Ocean and the Peninsula Watershed until you reach the summit at 1,314 feet.

At the top of the summit, enjoy the panoramic views of the entire Bay Area that make San Bruno Mountain one of the most unique places to hike in the Bay. The trail crosses Radio Road and continues eastward, snaking through Kamchatka rock outcrops and the junctions with the Dairy Ravine Trail and Eucalyptus Loop Trail.

Flora & Fauna

Enjoy diverse riparian plant communities, savannah grasslands dotted with wildflowers, coastal scrub, and some poison oak.
