This is a very short trail, but worth the ride at least once. It's got some technical stuff on it like stream crossings, stumps, steep hill, trees to get over, man-made bridges, etc. It hugs I-10 just a little before veering into the woods behind a subdivision. Good quick workout.
Located on Timberlane School Rd in Tallahassee, Fl on the South side of the I-10 bridge. Park on the side of the road. You will see an official bicycle trail marker on the steep hill. If you enter this road from Timberlane, then it will be on your right after you go under the overpass. If you come from Live Oak Plantation Rd, it will be on your left before you go under the overpass.
