This legendary climb takes you to the highest and longest peak in Southern California, ascending through the picturesque San Bernardino Mountains. Starting from the U.S. Forest Service Mill Creek Visitor Center, you'll face varying weather conditions, with hot summers and stormy, chilly winters adding to the challenge. The road leads you all the way to Big Bear Lake, offering stunning vistas of dense forests, rugged mountain terrain, and expansive valleys below, making it a rewarding experience for those willing to brave the elements and enjoy the beauty of the San Bernardino National Forest.
