Running 225 km (140.5 miles) from Lebrsnik in the Dinaric Alps to Ploce on the Adriatic Sea in Croatia, the Neretva is Bosnia’s longest river. The waterway is fed by five tributary rivers, including the Buna (overlooked at its source by the Blagaj Tekija monastery) and Trebižat (home of the awesome mini-Niagara at Kravice Falls), before flowing through Lake Jablanicko and turning southwest toward Mostar. The icy upper reaches of the emerald-green river near Glavaticevo flow through dramatic canyons and limestone gorges, but lower down the current is managed by four large hydroelectric dams.
On its way into Croatia, the Neretva flows underneath the historic Stari Most (Old Bridge) in Mostar, which has come to symbolize reconciliation between the Christian and Muslim communities since the Balkan Wars of the 1990s. From there it meanders past the historic town of Pocitelj, which sits high above the river amid the ruins of a medieval fortress and the Ottoman Hajji Alija mosque. Once into Croatia, the Neretva broadens out into a delta fringed with reeds and lilies and covering more than 260 square kilometers (100 square miles).
Much of the course of the Neretva can be followed by car; upriver it is a popular destination for white-water rafters and climbers in summer. Glavatičevo is the main destination for rafting adventures on the river.
