Switzer Falls - La Canada, CA
From the La Canada/Flintridge area (Highway 210), turn north on Highway 2 until you arrive at the Switzer campground area roughly 10 miles away. From the parking lot walk to the right, descending into the picnic and cabin area, over the wooden bridge onto the trail.
This is an out and back trail, and keep in mind that though it's an easy downhill beginning, the return back up is tiresome.
The falls were just a small trickle when we visited, so we continued down the mountain a couple miles, then back up.
