The most important rivers
There are numerous songs and poems written about this river, and it has been a muse to painters for centuries. It is said that river Una got its name from a Roman legionary who exclaimed "one and only" (Italian "una") when he caught sight of the river. One of the particularities of Una is its calcareous character which becomes manifest in the numerous limestone caves and islands. Thanks to its green colour, the river is also called "emerald river". The whole region from Martin Brod to Bihac is described as "emerald valley". Accordingly, the biggest ecological organisation of the area is called "Unski smaragdi" (Una emeralds).
River Una has its source on an altitude of 480 metres and in its very beginning it receives a couple of confluents before it continues into the valley. In the beginning it stretches through a very narrow canyon before it dilates to show its full beauty. In Martin Brod its first bigger confluent Unac joins, rich with fish. The two most gorgeous waterfalls are, amongst the large number of rapids and cascades, the famous waterfalls of Martin Brod and Strbacki Buk. The highest speed of the river is about 3 m/s.
A new finding of an Italian speleologist in June 2007 shows another very interesting feature. The cave diver Luigi Casati dived 250 m deep towards the spring where he measured a temperature of -100ºC. This is a record value on the whole area of Croatia and Bosnia.
Several times, river Unac wells out from the ground and drains off again. Its Black Spring represents a very special phenomenon when it bounces out with 5000 litres in one second. From there it flows through the valley all the way towards river Una in Martin Brod. That is where Unac is the richest with fish, especially with grayling. Its water is even colder and cleaner than Una which is very suitable for refreshment during summer time.
The only 6 km long mountain river flows through a poorly populated area between two rocky valleys and represents the most pristine and preserved territory in the whole region. For nature lovers, cormorants can be of great interest which gather her because of the high fish presence.
The river with a length of 4.5 km emanates approx. 5 km from Bihać in north-western Bosnia. In-between the scenic Plješevica Mountains, the river flows with a constant temperature of 8-10°C through the homonymous village which just consists of a several private houses. However, the biggest part of Klokot lies in a completely unspoiled nature before joining River Una.
Klokot is a mountain river with the typical characteristics of a karst river. The banks are soft and earthy, the river ground is overgrown with water plants which, in turn, offer habitat for a huge number of endemic crayfish. The river banks are lined with poplars and willows. Thanks to numerous cataracts producing big quantities of oxygen, an ideal development of the young fish is guaranteed.
