This was the greatest of all adventures. We left early in the morning so we could be the first visitors to the cave. Pook's Hill is not far. Our guide and driver was Hector and I am sure he is the BEST guide there is. He explained everything to us and guided us literally every step of the way. Wading, swimming, and climbing for 3 hours. At one point Hector told us we would be climbing up a 16 foot boulder - he helped us find our footings and hand holds and made us feel confident. This is something you can't imagine till you see it. I can't believe they even allow tourists to be in the cave with all the artifacts laying about. Nothing like it anywhere!
