North of Dayton there is Taylorsville dam park and trails. Round loop is about 7 miles.
Near Germantown, rugged trails but plenty of length along twin creek, I think it is a state park but can't remember the name. Between Bellbrook and Centerville are a few good hiking trails. The one out of these most similar to Clifton Gorge is Taylorsville Dam on rt 40 just north of Huber Heights and east of Vandalia.
Englewood Dam has some decent trails, but very short.
If you go to Taylorsville another good trail close by (1.8 mile long) is Charleston falls, a Miami County park on Ross rd. It currently is closed due to high volume during covid. I have walked that loop an estimated 6000 times and my wife about the same number. We like it.
