The hook
A paved car-free trail running straight down the San Andreas Fault, along two reservoirs, past a laurel tree older than California.
01Why it's worth it
The Crystal Springs reservoirs don't just sit near the San Andreas Fault, they fill the rift valley it carved, a long straight trough you can read in the land. The Sawyer Camp Trail runs six flat, paved, car-free miles down it along the water, which makes it a peninsula institution for walkers, runners, and cyclists. Midway stands the Jepson Laurel, a California bay laurel over 600 years old, the biggest and oldest known in the state, already a century old when Columbus reached the Americas. So you're moving down the most famous fault line on Earth, beside drinking water piped from the Sierra, under a tree that predates California itself. It's busy and paved rather than wild, but the geology and that tree give it real weight.
02How to experience it
Enter from the Hillsborough (north) or Highway 92 (south) gate. It's flat and paved, ideal on any bike; ride or walk to the Jepson Laurel at the midpoint. Weekday mornings are calmest. Pair it with Pulgas Water Temple and Filoli on nearby Cañada Road.
