E' lo specchio d'acqua tra Drvenik island e Krknjasi islands
...Blue Lagoon in Croatia is not your usual blue lagoon created by the coral reefs found around tropical islands forming a shallow lagoon with the crystal clear blue sea inside. There are no coral reefs in Croatia but that doesn’t mean that there are no blue lagoons. Blue lagoons in Croatia are usually formed between a number of small islands which are usually separated by the shallow lagoon between them that we like to call blue lagoons.
Since the Adriatic sea around the Croatian islands is always crystal clear the shallow water inside the lagoon is immaculately clear so you can easily see all the way to the bottom of the sea. You can even see all kinds of fishes and other sea animals from the lagoon bottom.
Because the sea inside the lagoons is always “clean enough to drink” you will sometimes find different kinds of sea urchins on the bottom. They are a natural sign that the sea of the lagoon is clear, healthy and not polluted. The sea urchins are not dangerous because they slowly move on the bottom floor. You should only take care not to step on them because of their spikes but since the sea is so clear it is definitively not a problem. You can easily see them even without the snorkeling masks. ....
