Requires 10 Days Advance Notice
Wow!!!!!! This tour is awesome. I would recommend this tour to anyone who wants the "real" caving experience. Loaded with climbing, water passages, and rappelling. The underwater kayaking is fantastic. Words cannot describe this experience. Great for any adventure group or just a guys or girls day out. Can't wait to go again. The tour guides are fun, knowledgeable and well trained. I loved it.....
