Steinhatchee is a small town on the Gulf coast and on the Steinhatchee River. There are no real beaches nearby. But if you like boating and fishing on the Gulf then you'll find plenty to do. Off hand I'd say there is not much else to do in the area. No hiking, springs or parks for example.
It is also well away from any bigger towns, the nearest would probably be Perry which would be an hour or so away. I don't recall seeing any major supermarkets or theaters there in Steinhatchee.
My wife had some relatives who lived there and we live about an hour away.
