Depending on where you want to start you can take Manker Flats Trailhead up past the Sierra Ski Hut on the main trial, summit Baldy then go north and catch (the other Devil’s Backbone towards Wrightwood over Pine Mountain to the Pacific Crest Trail (Approximately 8 total miles from Manker Flats). From there you can head south on the PCT downhill to the 15 freeway (20.2 miles) go under the freeway and continue on the PCT going due east past Lake Silverwood (Campgrounds here) 13.5 miles. Then you can continue on the PCT east past Lake Arrowhead to an area just north of the Lake called “Deep Creek Hot Springs” (21.7 Miles). Then continue on eastward to Big Bear Lake area Delmar Mountain Road (26.6 miles) (just north of Big Bear Lake) then head east to the end of Baldwin Lake which will turn south towards Mission Creek Trail Camp (41.1 miles) which is just below the 10,000 foot ridgeline leading up to Mount San Gorgonio.
Or you could take the Ski Lift up to Baldy Notch and start with a little mechanical assistance from Manker Flats area - it's just another mile up the road to the lift's. That would put you at higher elevation to start your hike.
It’s here at Mission Creek that you leave the PCT and take Fish Creek Trial 9.5 miles to the summit of San Gorgonio – and from there it’s a toss up which way you want to go – you can take the San Bernardino Peak Divide Trail due West for 18 miles and come out in the town of Angeles Oaks, or catch the Vivian Creek trail about 1.5 miles off the summit of San Gorgonio and take it down to Forest Falls (8 miles).
Just doing the shortest way possible suggested here is approximately 149 miles, that’s more than most could do in a three day jaunt. You might consider doing Mount Baldy, West Baldy, Harwood, Dawson, Pine and Wright Mountains in a fun one day trip then get a ride over to Forest Falls and go up Vivian Creek to summit San Gorgonio and do some of the other summits close by there – Jepson, Charlton, Lt Charlton, Dobbs, Shields, Anderson, San Bernardino and many others.
If you need to refine your plans, keep posting your thoughts or changes and you will get lots of help on this board. If you need to look at some of the maps I used for reference you can go to
http://www.hikertrash.net/ and look at the PCT maps located here and look for sections C3 all the way down to D4.
Others on this board may have a way to go from the 15 Freeway under the two lakes Arrowhead and Big Bear and avoid some of the extra miles but I'm not familiar with those trails.
Good luck - lilbitmo
