From the parking lot, there are 3 paths that will get you to the limerock road (a limerock path, and two short warm up trails). Take a left on the limerock and go under the overpass (very gravely/sandy conditions on both sides), then make a right at the information board on the other side.
This southern trail is an easy trail for about a mile with very few obstacles and very low incline climbs. You'll be riding mostly on well packed sand or dirt until you come across the limerock road again.
Cross the limerock road and continue onto the fast flowing S-curves and the start of multiple quick descents followed immediately by steep climbs. The trail is mostly well packed but you'll have to fight for grip with fallen leaves. Go on for another mile until you reach the wooden ramp.
After another mile of little descents and climbs you'll finish an extended climb to a nice opening off to the right. Shortly after reaching the opening you'll come back down to meet up with the limerock road again. Cross it for the last fast section that comes back around to the limerock road again where you'll enter an open sandy section that will take you to 484. This section is considered Nayls South.
