Una

Located in northwestern Croatia, the beautiful river Una is one of the most stunning in Europe. Rising in the Učka mountain, it flows through Gorski Kotar, forming a natural border between Croatia and Bosnia & Herzegovina. Along its stretch between these two countries, known as the Unac, the river boasts an abundance of rapids and falls, making it a popular destination for white water rafting and kayaking.
With a total length of 212.6 kilometers, the Una is a typical lowland river, with few high and steep banks. Its waters are usually crystal clear, with a few areas of darker water due to peaty substances. The river is home to a fairly healthy fish population, including bass, chub, and huchen in its deeper parts.
The Una is home to a total of 69 rapids and waterfalls, with the main section running from Martin Brod to the village of Bosanska Bojna in Bosnia & Herzegovina. The most well-known rapids include the Martin Brod Rapids and the Strbacki Buk. The former, which is 1.5 kilometers long, consists of several class II-IV rapids, offering thrilling white water rafting and kayaking experiences. The latter, one of the largest and most powerful rapids on the Una, features a vertical drop of over 30 meters.
