It really depends on your interests. There are a ton of little ice cream shops to find. If you like history you smack into something someone marched through or fought on frequently. The Cornwall Iron Furnace is close to Annville and is the only intact iron furnace left around here, I believe they cast the canons used in the revolutionary war.

Lots of pretty trails, especially Mt. Gretna.

In Lancaster county, there’s lots of tourist stuff, I enjoyed wandering around Lititz. The Tomato Pie cafe is good.

Check YouTube for videos on touring towns in Lancaster county. I’ve seen videos on Hershey as well.
