Front Line Road is in the 823,000-acre San Bernardino National Forest just south of Big Bear Lake. It provides a casual meandering adventure alongside a shallow canyon formed by the 8,000-foot San Bernardino Mountain Range to the north and the 10,000-foot San Gorgonio Wilderness mountains to the south. There are numerous places to pull over for lunch or to take in the many commanding views of the mountains and tall pines that guide your way.
