The most attractive locality on the Trebižat river is certainly the waterfall Kravica, 3 km downstream from Vitaljina in Studenci, near Ljubuški. It was created by the flow of the tuff surrounded Trebižat river and as a natural phenomenon it's under the country's protection as a natural rarity.
The height of a waterfall varies from 26 to 28 metres, with a water amphitheater under the waterfall with a diameter of 120 m. Over the tuff filled layer, from the top to the bottom of the waterfall, many plants such as grass, moss and ringworm grew. Along the waterfalls hemp, figs and poplar have sprung up. Next to the waterfall many mills and stoods for rolling cloth were once active.
