Fish Creek Canyon

Found this hiking spot in Duarte, CA.  It is only open about 10 Saturdays a year, as it is private property owned by a mining company.  Parking is available at the company's site, and they offer a van to take you past some old mines, and to the opening of the path.  It is a beautiful hike, that ends at a beautiful waterfall.
