We have not been able to confirm the surface, distance or shape of Hidden Valley Open Space yet from its own listing, the park's website or runner reviews — so those cells stay blank rather than guess. What is below comes straight from the listing and from reviewers' own words. 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 Hidden Valley Open Space
A perfect place to go for a walk. Slightly steep, but you'll probably be so lost in appreciating the wild flowers and views along the way, that there'll be no time left to notice the fatigue. Visiting around February is the best time since the flowers don't last long I hear.
