You can take the trail to the left, front, or right. I usually take it to the right. The thing that is great is that you can take multiple routes. You really need to just spend some time exploring the trails. After going a few times I had a good grasp on where to go. Some of the trails dead end into a road. You can either see it's connection accross the road or you get on the road travel a little way and you will see another trail head. After a ride through it, I am at 5 to 6 miles on my odometer. It is a network of trails. Not too hard, but still tech. enough to be fun. For how close it is, it is fun to use. Watch out for people as they often don't know what to do when they see you. There is also a large tree off the trail that is covered in spray paint, exspect to see pot heads in the area and the smell of marijuana in the air. Be careful there because they will not respond to your communication. You will say, "excuse me" and they will walk right at you like they don't think you are real. It is a trail system worth checking out though.
The park is right off of I-64. Take the Grinstead Exit. Take a left on Lexinton road. Take a right on Ledge Rd. Follow the loop. You will wind around until you reach the top of a hill. Drive a little further. You will see a kids playground on your right and a large white fountain on your left. Park your car by the fountain(if available). The trail head is right there next to the fountain.
