The valley of the river source is called the Trenta valley and it is one of the most beautiful valleys in Slovenia. That is very hard, because there is a big competition among many other beautiful valleys in Slovenia. The valley as well as a big part of the Slovenian Alps was researched by a botanist, philosopher, researcher - Julius Kugy. In memory of him there is also a monument near the spring of river Soca.
The river is so clean, that's why it has a beautiful bright blue color and a lot of animals find their home in the river or near it. An example is the Soca trout. It is quite famous and it is good to eat as well. The last years the American trout has been pushing out the Soca trout, because they are more aggressive. The scientists are trying to save the fish, but it's going to be very hard and it's going to take a long time.
