This is the easier side of the trails at the <a href="http://www.tripleblaze.com/3/1293/Hiking-Trails/Georgia-International-Horse-Park.html">Georgia International Horse Park.</a>
This trail winds through the woods and is very moderate.
Note: The Georgia International Horse Park was the site of the cross-country race for the 1996 Olympics. This is still a very popular mountain biking trail, so just be aware when you head out.
From I-20, take Exit 82 "Georgia International Horse Park." Go North on 20 (or East on 138) for approximately 5 miles. There will be signs to turn right for the Horse Park. Large gravel parking area on the right.
