Mt. San Antonio, commonly know as Mt. Baldy, reaches to an elevation of 10,064 ft and is the highest peak in both Los Angeles County and the San Gabriel Mountains.

Routes

Here are two graphs and an interactive map showing some of the common routes up Mt. Baldy and their elevation profiles. I will add descriptions and more routes as time allows.

Route Distance (1 way) Elevation Gain/Loss* Devil’s Backbone (Notch Route) 5.9 +4306, -472 Ski Hut (Baldy Bowl Trail) 3.9 +4065, -231 Register Ridge 3.6 +4218 -387 Bear Canyon (Mt. Baldy Trail) 6.2 +6534, -811 North Backbone 6.6 +5375, -2567 * Elevation numbers pulled from Google Earth.

Variations & Combinations

Since 3 of the routes (Devil’s Backbone, Ski Hut & Register Ridge) all start at Manker Flat, people often combine the routes to form a loop. Two common combinations are a Ski Hut ascent & Devil’s Backbone descent (referred to as the Baldy Bowl Loop) and ascending via Register Ridge and descending via Ski Hut or Devil’s Backbone. Other variations include:

using a short car shuttle in order to form a semi-loop with Bear Canyon & the Manker Flat routes taking the Mt. Baldy Ski Lift to Baldy Notch to avoid hiking the road in winter, hiking to the Sierra Ski Hut then climbing directly up the Baldy Bowl hikers using Bear Canyon or Ski Hut will sometime summit West Baldy, which can be hike with a small detour



I will add graphs showing some of these routes soon.
