Located in beautiful southeastern West Virginia. Organ Cave is full of wonder, science and history. What other cave can you visit and see not only all the natural wonders, such as bats, rock formations, and fossils, but where over 1100 Confederate soldiers hid for 3 winters from the neighboring Yankees. Organ Cave is a National Natural Landmark plus a National Landmark of Historic Places and also on the Civil War Trails.We also offer fossil hunts as one of our expeditions. This cave has over 45 miles of mapped passageways with still over 200 leads yet to be mapped and surveyed. These leads can go on for miles yet unknown. When The History Channel was here in 2008, they found in their research over 70 miles of passageways. Organ Cave is the second longest commercial cave on the east coast. It is located in the heart of beautiful Greenbrier County of West Virginia.
