ALTERNATE ROUTES

It is possible to hike from Dawson Peak up to the summit of Mount San Antonio. Wright Mountain, Pine Mountain #1, Dawson Peak, and Mount San Antonio make a popular trip.


SPECIAL CONDITIONS

The ski lift at the end of Baldy Road operates in the summer months on weekends and some holidays. It is possible to take this (for a fee) to Baldy Notch. This significantly reduces the gain and distance from this direction.

HISTORICAL NOTES

This peak is commonly know as Mount Baldy. It is the highest point in the San Gabriel Mountains and Los Angeles County. The road and trail to the summit were originally established by gold-seekers in San Gabriel Canyon.
