Patience is key on this one but the end is a breezy reward. The elevation is gradual in most areas which is tolerable, with a handful of steep corner turns as you go up. Going down, watch your balance as the decline can get sharp as well. This is rated a 3.5 hour roundtrip hike for 7.3 miles long. It's possible to take this in less time. The top of this location is also a campsite though no one was there at the time. A rewarding breeze wafts under the shade of the tall trees around you as you enjoy the view down to the San Gabriel Valley. On the downhill back to the start, we found there was a shortcut that was more steep as well and less traveled but clearly marked as a path. If you need to get back to the urban, this is the route to take. Would also recommend just having some type of map (google or apple maps) on your phone to make sure you're heading the right way back to the start. And bring plenty of water and wear lots of sunscreen, a hat and/or sunglasses, and a towel too for the buckets of sweat as well.
