Here's a
topo map of the Mt. Baldy area. Hope it's helpful.
A = The start of the service road in Manker Flats. Go up this road toward San Antonio Falls. The road will switchback as it approaches the falls. Stay on the road.
B = The road will turn a corner and go along the S face of the ridge here.
C = A bit beyond the turn, look for a trail leading left up the high side of the road.
D = You'll come to a metal trail register here on a post. This just confirms you're on the correct hike. There is an alternate route that proceeds from here, but save that for another trip.
E = The ski hut. You should be able to see the hut periodically as you ascend. The map shows the trail ending at the ski hut. This is incorrect. The trail turns left (west) here and traverses across Baldy Bowl. There is water generally available either in the ski hut or a nearby spring.
F = Approximate location of the trail as it traverses across Baldy Bowl. The trail can be faint in spots, but keep your eyes open; it's definitely followable.
G = The trail will gain the south ridge of Baldy at approximately this point. Now all you have to do is essentially head up the ridge to point "H."
H = The summit of Mt. Baldy and the highest point in LA County.
I = Harwood-Baldy Saddle. Head down the trail that goes down the E ridge of baldy to the saddle, then follow the trail around Mt. Harwood to the next point:
J = The Devil's Backbone. Interesting very narrow section of the trail on a knife edged ridge. Intimidating for some, but not bad at all for an experienced hiker -- except in winter.
K = Eventually the trail turns to a road. The road(s) here in reality don't look like the topo. If you toggle to Satellite view, I think you'll get a better idea of what's there. Essentially, all you have to do is to follow the ridge down to:
L = Baldy Notch. There is a trail sign here under a tree on the south side of the notch. From the notch, proceed to:
M = The snack shop! You can rest, re-hydrate and what not here. From here, you can take the ski lift to:
N = The bottom of the ski lift and road's end. From "N," simply walk back to your car.
Alternatively, if you'd rather not take the ski lift, simply follow the service road from "M" back to your car at "A".
HTH,
