Ngardmau Waterfalls are located in the northwestern part of the largest island of Babeldaob. The highest mountain on Babeldaob island, and the whole of Palau is Mt Ngerchelchuus, 217 meters high, of which descends a network of streams and small rivers, one of which is Ongimi. Ongimi forms Ngardmau Waterfalls, the highest waterfall in Micronesia. Visitors love to visit this place, because of the view of the beautiful waterfall, and of the nature that surrounds it, and the opportunity to swim in the natural pool of crystal clear water at the foot of the waterfall.
