Points of Interest

1. Trailhead - San Bruno State Park

The trailhead for both the Summit Loop and Ridge Trails begin at the South parking lot. Enter at the main State Park entrance, proceed past the first parking lot and continue under the road to the South lot.

3. [JCT] Summit Loop/Ridge Trail

4. [JCT] Summit Loop/Dairy Ravine Trail

Returning Summit Loop hikers should continue downhill in either direction, although the left-handed trail will get you back quicker.

5. End of Ridge Trail

You won't find a definitive end to the Ridge Trail, and we draw our line here with some nice views overlooking the South San Francisco and Brisbane shorelines.

Should your appetite for hiking continue then feel free to proceed onward as the train heads further downhill and increases in steepness.
