Twisting, rooty singletrack loops through Georgia pine forest. The main or "advanced" loop is about 8 miles all told with a couple options to make things easier or to shorten the ride. Bring a map or a friend - this place can be confusing despite the (minimal) signage. This trail will host a Dirty Spokes 6 hour race in 2009.
To get there take 441 south from Athens to Farmington (about 15 minutes) until you see a large pavilion that says Oconee Heritage Park on the right.
