Cave tubing is really great....lots of fun...we went with Caves Branch 3 years ago and enjoyed it immensely. The caves were DARK..the only light we had were on our foreheads...had a picnic inside the must be prepared to get wet (no sun to warm up in) to wear hiking boots (they will also get wet. WE DID A GREAT AMOUNT OF LAUGHING WHILE PADDLING ALONG!
