The Landis Valley Museum is a very interesting and large museum. It's basically a small town recreated for visitors--houses of different eras, a schoolhouse, firehouse, general store, blacksmith shop, and so on. We found the blacksmith shop to be the most interesting because the smith working was very informative. I wouldn't recommend it on a very hot day, or for people with mobility issues--when we went, the walkways were dirt/gravel. Small kids probably wouldn't appreciate the museum, but for older kids and adults, it is very intriguing.
