Turkey Run x3! Fantastic hiking trails! It's popular in the fall due to the covered bridge festival & fall colors, so reservations are strongly recommended. Arguably the most popular park in the state.
If you are wanting to visit the area north of Indy, Prophetstown SP near Lafayette is nice. Definitely get a FHU pull-thru - better sites than the others.
