My husband and I just stayed in Tappan Lake. It’s a little over an hour from Pittsburgh and the cabins are new and right across from the lake. We got the mini lodge because they were running a bogo special that’s going on until the end of February. There isn’t a lot to do there but they have a store with food and drinks and the marina is a mile away with a restaurant and bar.

We also love Deep Creek, Hocking Hills (a little over 3 hours), Cook Forest & Treasure Lake.
