Stockton Flats is a short drive from the densely populated Inland Empire and takes you deep within the 200,000-acre Front Country Ranger District of the San Bernardino National Forest. The trail lies at the eastern-most extension of the San Gabriel Mountains. The trail offers a chance to leave civilization behind and see what this rugged country looked like 100 years ago. Only a few weeks of the year does snow stay around, bringing a quiet to the forest that is only interrupted by the occasional sagging tree branch dropping snow. Pets are welcome but must be kept on a leash.
