Confirmed from Green Hills Park's own listing, the park or land manager's website, and runner reviews. Blank cells mean we could not verify that fact — we would rather say "not reported" than invent one. There is no Easy / Moderate / Hard rating on this page on purpose: a one-word difficulty score tells you nothing about whether a trail suits your run. Surface, distance, shade and hours do.

What runners say about Green Hills Park

Pulled from public reviews of this trail (51 of them) — the things people bring up again and again, in their own words. Nothing here is written by us.

Green Hills Park is located in a quite neighborhood in Millbrae, CA. I was able to enjoy a few hours at the park after purchasing lunch at a nearby Taco truck. There is a bronze memorial plaque at the park for a pedestrian who was killed at the crosswalk. This was spooky.

★★★★★ — Eddie , Feb 2022

Great little park in a prime location. Perfect to let the kids run! Usually quiet and clean. No bathrooms, but great picnic spot.

★★★★☆ — Leah , Mar 2017

  • ShadeNot reported. Assume some of it is exposed and carry water in summer.
