Criteria
The criteria used for compiling this list was that the hike can be done within 24 hours and generally involves a hike to a single peak. The exception is when it is necessary to go over another peak to get to the objective on the designated route (e.g., going over Mt. Baden-Powell to get to Ross Mountain or going over Iron Mountain #1 to get to Mt. Baldy along the San Antonio Ridge).
Note that the criteria used excludes hikes where you just string together multiple peaks in a single day’s outing. There’s virtually no end to the combinations (and challenge of course) that can be put together on that basis.
The hikes listed here all involve out-and-back routes except for the loop routes for Iron Mountain #1’s north ridge (No. 1) and southwest ridge (No. 2a) and the point-to-point routes for Iron and Mt. Baldy along the San Antonio Ridge (Nos. 3 and 4).
I welcome comments and suggestions as to challenging day hikes in the San Gabriels meeting the criteria above that should be added to this list.
