Fun long hike from Sierra Madre. Great to start out in the city and hike so far out of it. Though it takes away from the sense of success when you get to the top and there's people driving golf balls from the parking lot into the canyon.
Many, many ascents over the years. Most of the ascents have been either by bike or on a trail run. Have done it from Bailey Canyon, Mt. Wilson Trail, Mt. Wilson Toll Road(biking), and from Chantry Flat.
