The Kaeng Krachang National Park is one of the largest in Thailand and sits right next to the Burmese (Myanmar) border. Pala U Waterfall is a beautiful spot to visit. You will pass through stunning countryside and hills on your drive there that will only take 1.5 hours or so. The waterfall has 16 steps, making it one of the highest in Thailand and those who make it to the top will be rewarded by superb views over Thailand and towards Burma. It should be noted, however, that progressing further than the third stage will be arduous and should only be attempted by those fit enough to do so.
