Points of Interest

1. Trailhead - San Bruno State Park

3. [JCT] Summit Loop/Ridge Trail

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.
