Whether it is an exciting river adventure or a more peaceful sea kayak voyage you are after, Croatia’s waters offer great potential. Despite the fact that the rivers’ water levels are more suitable for experienced kayakers in spring, whilst the summer lows are recommended for beginners, almost all the rivers offer a variety of levels of difficulty. With the Dobra, MreĹžnica, Una, Kupa, and Korana in the north and the Cetina or Zrmanja in the south that sit in the middle of National Parks, a trip on a kayak offers many undiscovered sights.
