I haven't read all the comments here so I don't know if it's been mentioned, but Columbia PA is a super cool gem of a place just outside Lancaster. It's right on the Susquehanna River and has a lot to offer for a small town! I spent a few hours there a couple of weeks ago and only just scratched the surface of all the offerings. The history is rich, the downtown area is well preserved and there are food, coffee, and alcohol offerings everywhere. The National Watch and Clock Museum is there (surely a niche museum if ever there was one). There is a trail along the waterfront on the Susquehanna River and plenty of outdoor activities in the immediate area. Turkey Hill has the "Turkey Hill Experience" on the edge of town if you like ice cream and iced tea. For antiquing, there are a couple of amazing locations in old historic buildings down along the river (one with some of the most incredible live edge raw wood I've ever seen at moderate prices). I'm planning a trip back this spring (from Bellefonte) and I'd love to hear if anyone has some "must-see" recommendations!
