Pioneer Tunnel Coal Mine Tour
This guided mine-car tour of an old horizontal drift mine two and a half hours northwest of Philly might seem like it’s going to be kids’ stuff. But then you’re more than a quarter-mile inside a mountain. (And yes, they turn the lights out.) Bring a sweater, because the tour lasts for half an hour, and temperatures inside the mine average 50 degrees.
