Between istria and the island of Cres the water falls down very steep. On the right side of the Beach you can swim along The wall until you See a carwreck at about 20 Meters deep. I saw a big tuna just 50 meters ... Between istria and the island of Cres the water falls down very steep.

Great place to freedive!!!
