We really enjoyed the adventure of this caving experience. One thing I do caution. To get through many of the tight spaces in this cave complex, no one with a larger than a American size 38 waist should attempt this adventure, Sorry. I am right there,and it was a real question if I would be successful, or stuck,and need rescuing with oil poured over my back and belly to get through. If you do make it through, the rewards are impressive. A wonderful adventure, especially for the kids.
