Although the majority of the waterfalls around Bali are turned into a profit machine – local supervisors charging entrance fees – there are still some that can be accessed for free. One of them is Air Terjun Pengempu waterfall located close to Ubud, in the area of Tabanan. The falling water streams into a pool with some spots deep enough to swim in. The highlight of local and foreign visitors is a liana, hanging down from a tree, which is used as a natural swing. It's great to watch Indonesian kids doing acrobatics on it.
