Hidden Boulder is a climbing area in Brown's Valley Ridge Open Space, a city-managed open space in California. The surrounding land is city land, and the boulders sit among a cluster of other climbing spots, so it works well as a stop in a day spent exploring the boulders of this open space. Spring and fall are the most comfortable times to visit. Typical averages from the nearby Vacaville weather station show April highs around 75°F and October highs around 81°F, while July and August average in the mid-90s. Mother Boulder is just 0.1 mile away, and Rump Roast and Y Boulder are each about 0.2 mile off. For a hike, Al Patch Track Footpath is roughly 4 miles away.
