This is a GREAT trail! It has many switch backs, creek crossings, and washboards. This trail is the best I've ridden in SC.
From Exit 76 on I-26, near Newberry, drive toward Newberry on SC 219 to the intersection with US 76/SC 34. Turn left, and drive to the traffic light where SC 34 splits to the right. The entrance to Lynches Woods is at a large sign on the left.
