Mount San Antonio

Mount San Antonio is a mountain summit in Angeles National Forest, California, standing at 10064 feet. The slopes display different vegetation zones, from pine forests at lower elevations to talus fields near the top.

Antonio Maria Lugo, a rancho owner, named the mountain around 1840 after Anthony of Padua. The area later saw the development of hiking and recreational facilities by local mountaineering groups.

The peak carries the nickname "Mount Baldy" because of its treeless summit visible from many parts of Southern California. Hikers and climbers use the area year-round, with conditions changing dramatically by season.

Several hiking routes lead to the summit, with access varying by weather and snow cover. Visitors should start early in the morning to avoid afternoon thunderstorms common during summer months.

A Sierra Club shelter stands at 8200 feet and offers overnight accommodation for mountaineers. The hut is supplied by snowmelt and serves as a base camp for summit attempts.
