Thomas exit off I-471, turn right if coming from the south, left if from the north. Follow Grand Ave.
Trails start at various points towards back of park.
Lots of other bike shops have them too, call around. Fork-a beginners paradise, boring after a while and stays muddy unless we're in the middle of a drought. 6 mile trail, but is further away from Cincinnati than Tower park. This is the most technical and best trail close to the Cincinnati area. If you miss the turn at the bottom of a couple of them, you go over a drop of 10-20 feet into the creek bed.
