Old Baldy—East Approach Professional Review and Guide
"No Southland hiker’s repertoire of experiences is complete without at least one ascent of Mount San Antonio—Old Baldy. The east approach is the least taxing of the several routes to the summit, but it’s by no means a picnic. You start at 7800 feet, with virtually no altitude acclimatization, and climb expeditiously to over 10,000 feet. With easy access, it's beguilingly easy to come unprepared for high winds or bad weather, which although fairly rare, may come up suddenly. Ice, if present, can be a serious hazard as well.
By mechanical means (a car) you can get to the upper terminus of Mount Baldy Road in less than a half hour from the valley flatlands below. Further mechanical means--the Mount Baldy ski lift--carries you to an elevation of 7800 feet at Mount Baldy Notch, where you begin hiking."
