Get ready for one of Bali's most magical sights, a stunning waterfall hidden inside a cave. To reach it, you'll take a 15-minute journey down a series of jungle stairs and then wade through a shallow river, which only adds to the adventure. The real showstopper is when the sun is high, sending incredible light beams down through the opening in the rock, illuminating the mist and water. It's a truly breathtaking scene and well worth the effort to get there.
