This park covers several expansive exposed hilltops near Richmond, CA. There are 22 miles of trails, most of which are fireroads. Theres singletrack available in nearby Tilden park, but all of it is off limits to mountain bikes. If youre interested in riding fireroads, then come check out Wildcat Canyon. If not, I recommend you just skip it. More information is available here: http://www.ebparks.org/Page151.aspx
