Mount San Antonio, colloquially referred to as Mount Baldy, is the highest peak of the San Gabriel Mountains, and the highest point in Los Angeles County, California. The peak is within the San Gabriel Mountains National Monument and Angeles National Forest.
Mount San Antonio's sometimes snow-capped peaks are visible on clear days and dominate the view of the Los Angeles Basin skyline.
The peak is pyramid shaped, with a steep south face (Baldy Bowl) and a shallower north face. The summit is accessible via a number of connecting ridges along hiking trails from the north, east, south and southwest.
The mountain is almost always referred to as "Mount Baldy" by locals, to the point where many would not recognize the name "Mount San Antonio".
The mountain was named by a local rancher after Saint Anthony of Padua. When American settlers arrived and surveyed the land, "Baldy", a reference to the bare fell-field of Baldy Bowl that dominates the south face visible from Los Angeles, became the predominant name, and it has stuck. Nonetheless, "Mount San Antonio" is the official name according to the GNIS, and is still used by a number of institutions (e.g. Mount San Antonio College).
The summit has two peaks: the main peak, elevation 10,064 feet (3,068 m), and a sub-peak, West Baldy, at 9,988 feet (3,044 m). The main peak marks the boundary between San Bernardino County and Los Angeles County. The mountain is in the Angeles National Forest.
The mountain's southern watershed drains into San Antonio Creek, the north side into Lytle Creek and the Fish Fork of the San Gabriel River. San Antonio and Lytle Creeks are part of the Santa Ana River watershed. San Antonio Creek descends through a deep canyon which has several waterfalls, the last about 75 feet (23 m) high.
