It seems clockwise is the best direction to go. From the parking lot you can access the trail in many ways. Just go to main sign and behind you'll see the main trail-head. About 20 yards behind that take a left on the trail for the fun to begin.
Be aware that this trail can get muddy and stay muddy for a long time after rain.
There are a lot of other trails in this park. The Southside Loop runs the perimeter and is the longest. It is a lot of fun but has a lot of roots. Some rougher climbs and downhills. However there are also some really flat sections that are fun also.
