Kravice pours over a cliff that its own water is building. The Trebižat River arrives carrying dissolved limestone, and at the lip mosses and algae pull that carbonate back out of the water and lock it into porous rock called tufa — the same living stone that raised the barriers at Plitvice and Krka further up the Dinaric karst. The wall it has grown stands roughly 25 metres high and splits the river into about twenty separate cascades, which drop through hanging moss into a pool some 120 metres across. The river feeding it is strange in its own right: it sinks underground and resurfaces so often on its way across the karst that it picks up nine different names along the route — Vrljika, Matica, Tihaljina and the rest — and only arrives here as the Trebižat. Forest closes the amphitheatre on every side, so in a dry, stony corner of Herzegovina the first view over the rim is of falling water framed by green.
Few waterfalls this size let you swim at their foot, and at Kravice the pool is the whole point. Swimming is allowed from June to September, when the water reaches a bracing 16–20 °C, and small boats row people out toward the curtain while spray drifts far enough to cool the entire bowl on a hot afternoon. Outside that window it is a different place: the flow falls away to a fraction of its wet-season volume by late summer, and in March and April the separate strands merge into a single thundering wall. Today the falls are a ticketed, state-protected park — a stepless walkway drops from the gate to the water, an old mill still stands beside it, and on July and August middays the coaches from Mostar and Međugorje arrive in force.
