An hour from Mostar, the Trebižat river fans out over a 120-metre arc of travertine cliffs and drops twenty-five metres into a broad green pool — and unlike at many of the Balkans' celebrity cascades, here you can actually swim. Paddle right up to the spray, or hire a kayak to wobble beneath the curtains. June brings the fullest flow; late summer the warmest water. Come early or stay past five, when the day-trip buses retreat towards Dubrovnik.
