We are big fans of caves, and in southwest Pennsylvania, our options to go underground are a bit limited.
Closer to the city it is much easier to find an old coal mine to go deep into (like at the Tour-Ed Mine and Museum) than it is to find a cave. But for those who want to make the drive in order to explore a gorgeous cave system (and the largest cave in Pennsylvania), the 90 minute trip to the Laurel Caverns in the southern Laurel Highlands is for you!
