Laurel Caverns is a natural calcareous sandstone cave system and the largest cave in Pennsylvania. Located about 50 miles south of Pittsburgh, it offers various experiences for visitors. You can take a traditional guided tour through the well-lit passages, suitable for all ages. For the more adventurous, there are opportunities for rappelling and wild cave tours that explore undeveloped sections of the cave. The constant 52-degree Fahrenheit temperature inside makes it a cool escape in summer.
