The often widely separated pick-up points for the participants naturally made the pick-up and drop-off process quite strenuous. Otherwise, both the driver and the guide were very competent and helpful. Of course, there were masses of people there, which somewhat dampened the experience. Everyone wanted the best photo, especially the Koreans and Chinese. The hike to and through the caves was almost even more beautiful than the large waterfall. Many tourists were too lazy to hike behind it, so we were practically alone and could enjoy it.
