Click on title of post to view photo in large format: The Una River in Bihac, Bosnia-Herzegovina. Bihac is popular with tourists who are visiting Una National Park, located just a few kilometers from the city. There are spectacular waterfalls along the upper course of the river, located just a few kilometers from Bihac. The river is also known for whitewater rafting trips and for the annual International Regatta, when boaters take to the water to celebrate the river, as well as for the beautiful turquoise color of its water on sunny days. Unfortunately, the sun did not come out during my visit, but even so, the river had an ethereal feel to it.
