Relax alongside waterfalls, caves, cascades and brook clear water. Cetina, the longest river (100km) in Dalmatia, runs out into the Adriatic sea by the town Omiš. The first part of the river is calm, but the second one is full of streams. The only thing you need to know before you go rafting is how to swim. Pack suitable clothes (swimwear, shorts, t-shirt and comfortable shoes like sneakers or sandals) and come along on a great adventure.
