This loop starts from Mt Wilson Trail Park in Sierra Madre and uses that trail, Manzanita Ridge, Upper Winter Creek, Mt Zion, and Surtevant in ascent of Mt Wilson and then the Toll Road and Mt. Hastings traverse to Mt Jones and back down to the Wilson trail and parking in decent. It takes all day.

Not for the casual hiker. The total elevation gain is more then climbing Mt Whitney (on much lower altitude, of course). This is a Very Serious Workout. Incredibly varied landscape with great views. Up to Manzanita Ridge (3,400 ft climb) is a good workout. The section across Mt Zion was a bit less crowded then the rest. The climb to Wilson from Sturtevant Camp is another 2,400 ft up but generally pretty. Mt Wilson proper is build up, but at least there are restrooms and there is a working bottle fill station next to the cafe (cafe currently closed because of fires nearby). The unmaintained part section after you more or less jump off the toll road is exposed but was wonderfully quiet (overgrown: long pants required). Will probably do this again.

Only the lowest portion of the trail is heavily trafficked. Also, once you go off the toll road toward Hastings the trail is not maintained so therefore steep and somewhat brushy. It is also exposed. This route would be really hot in the summer but is fine for all but the hottest months.
