A short, gorgeous, and for the most part family-friendly, after only a few minutes into our hike I knew Millard Canyon Falls was going to be on my list of favorite waterfall hikes in SoCal! Located near Altadena, CA, according to AllTrails, Millard Canyon Falls is 1.2 miles round trip with only a 256-foot elevation gain. When my husband and I did the hike we tracked 1.58 miles with a 371-foot elevation gain. We spent only 90 minutes on the trail with about an hour and 15 minutes of that moving.
