Summary: Little Santa Anita, or LSA as it is generally called,  is one of the most popular canyoneering routes in the San Gabriel Canyons. Just off the Mt. Wilson Trail this canyon has flowing water year-round.  Unfortunately, due to a recent fire and subsequent land slides many of the pools and slides the canyon was known for were filled in.  The extremely wet winter of 2010/2011 did an amazing job of restoring the canyon almost back to its pre fire state.

Due to its relatively short drops and easy access this is a great canyon for beginners and even first descents.

Little Santa Anita Canyon is a pretty straight forward canyoneering adventure.  There are many small drops all of which are pretty straight forward rappels.  The canyon can be done using natural anchors for most of the rappels, however years ago the canyon was bolted.

Approach and GPS

The approach to Little Santa Anita Canyon pretty much as straightforward as they come in the San Gabriel Valley area.  The GPS track below takes you up the Mount Wilson trail from the trailhead to the first water marker.  Once you reach the marker the trail splits, take the fork that heads down to the stream bed.

  1. From DA on FB: Ran LSA last night. Still dry at the bottom but I was glad for my 3mm suit at the top.
