About the event

Baldy Ascent Challenge: Mt. San Antonio via Manker Flat
DETAILS- #MTBALDY #MTSANANTONIO #PEAKHIKE
No peak in the San Gabriels is as iconic as Mt. Baldy (Mt. San Antonio) — the tallest mountain in LA County at 10,068 feet. On a clear day, you’ll spot it snowcapped from miles away. As Jerry Schad said:
“No Southland hiker’s repertoire of experiences is complete without at least one ascent of Mt. San Antonio.”

This is one great hike and a true SoCal rite of passage. Expect a challenging climb, big elevation gain, and the reward of panoramic summit views stretching to Catalina and the Pacific.
