The trails are signed easiest, more difficult, and most difficult. The San Bernardino National Forest encompasses the San Bernardino mountains, San Jacinto mountains and San Gabriel mountains, a large, more than 800,000-acre area that gives you your pick from dozens of trails. Holcomb Creek OHV trail is a challenging 8-mile trail spanning a boulder field. The Cactus Flat OHV area is a wide, 25-mile loop trail that is popular with 4×4 riders. The 3,200-acre Summit OHV Area offers plenty of room for outdoor adventures, and is a good place to stage for the Cleghorn Ridge OHV Road, a scenic, nearly 15-mile trail rated for moderate ATV experience that features miles of beautiful wild flowers. Coxey Road is a 19-mile trail that offers an easy ride past campgrounds, lovely meadows, ridges, and scenic peaks. As you might expect, the Gold Fever Trail, a 20-mile trail best traversed with a high-clearance vehicle, takes you through the beautiful Holcomb Valley, which was a thriving gold rush area in the mid-1800s.
