The biggest semisubmarine in the Adriatic

BIG MARLIN

Semisubmarine Big Marlin is the biggest, original and innovative ship in the fleet of semisubmarines that offers you a unique experience of underwater sights. Although it looks like a real semisubmarine, Big Marlin does not dive, yet it has an underwater cabin from which you can safely enjoy the tour. You can see the spectacular waters of the island from the comfortable and spacious cabin while at the same time you can enjoy the views of the town of Krk, as well.
