The 200m high Kadishi Tufa Waterfall is the world’s second tallest tufa waterfall. It is known at the ‘weeping face of nature' because the formation is said to look like a face that is crying. Unlike other waterfalls Tufa waterfalls grow rather than cut into the underlying rock. This is caused by the water which emerges from underground rich in calcium, and deposits rock formations more rapidly than they erode the surrounding rock.
