These trails run from the soccer fields on Henderson to the fields on Chamblee Tucker side. Some are difficult with plenty that are easy. They are not used much. The Lake and picnic area in the middle of the park make a nice base for rides.
How to get there:
Off I-285, take La Vista and head NE. Turn left on Henderson. Park is 1 or so miles on the right. You will see the soccer fields first. Look for the trails leading into the woods.
