Hidden in the middle of a beautiful nature reserve, the "ivory tusk" waterfalls descend a series of seven tiers amid a mass of ochre-brown rocks. Two branches - or "tusks", hence their name - separate on the third level, adapting to the whims of nature before plunging into a wide pool of crystal-clear, cool water. It's a great feeling to swim in this natural swimming pool (be careful of the slippery rocks) after the strenuous walk here, as the paths leading to the top of the falls are quite challenging.
