Fall Line

Fall Line is a mountain biking ride in California's San Bernardino National Forest, within the Mountaintop Ranger District, about a mile from the Forest Service's management area. The route is an out-and-back of about 2 miles, with a total elevation gain of 489 feet, from a low point of about 7,144 feet to a high of about 7,641 feet. It is a moderate climb, so plan for a steady effort over the course of the ride. For comfortable weather, late spring and early fall are the sweet spots. Typical averages from a nearby weather station at Big Bear Lake run highs around 66°F in May and 73°F in September, with only a couple of wet days a month. That station sits roughly 888 feet lower than the route's high point, so temperatures on the climb run cooler. The route sits close to several other outings. The Skyline Trail and the Bristlecone hike are both within a third of a mile, Buttercup Group Camp is about 0.7 miles away, and Big Bear Lake Recreation Area, roughly 3 miles off, offers lake fishing.
