Cherokee Park- central louisville (usually the closest) – pretty technical but well planned out fun trail system
Waverly Park – well built, flowy trails with some good elevation changes
Turkey Run (Parklands Park) – easier, flowy trails
just outside of Louisville:
Fort Duffield- backcountry/techinical
Obannon Woods- Largest/most spread out trails
All have their own individual flavor but can’t go wrong with any of them!
