If you find your self alone in this part of Dalmatia first time, it's better for you to stay out of finding this oasis. Meaby strange conclusion but true, for this piece of nature know's only local residents, and in most cases they dont want sporadic visitors to be those who also enjoy in Zrmanja river. Main reason for that is fear of pollution, and this is their original way to keep place clean and wonderfull.
But if you have lucky as me, than you will find your guide for adventure in Mokro polje (Wet Field), in area of Croatian city Knin, 3 km before Zrmanja turns on west.
Most time as you get closer to this specially place, you will fill just like someone who go deeper and deeper in the magic labyrinth, and then, suprisse! Pure and wild nature offers what is most needed in the days of tropical heat. Very cold water in which at first seems it's impossible to get, but only half a minute of courage and you're in the best possible relaxation pool for body and soul.
In addition, this is one of the rare places in area that does not have any neighboring house, so the water is perfectly clean, not just for swimming, but also for drinking.
