Clark's Grade is a mountain biking route in California's San Bernardino National Forest, within the Mountaintop Ranger District. The Forest Service manages the land, and the ride is an out-and-back of about 7.6 miles with a one-way elevation gain of 1,636 feet. The climb starts at a low point of about 6,164 feet and reaches a high of about 7,815 feet. Summer is the most comfortable time to ride. Typical averages from a nearby weather station at Big Bear Lake show July highs around 80°F with lows near 50°F, and the station sits roughly 1,000 feet below the route's high point, so temperatures up top run cooler. Clark's Ranch and the Big Bear Secret Trail are both within about 1.6 miles. Climbers can head to Siberia Creek Tower, about 2.2 miles away, and Big Bear Lake offers fishing about 3.8 miles off.
