Submarine adventure is a perfect Krk boat tour for children and adults of all ages, so you can be sure that the whole family will enjoy it. Experience the underwater world of fishes and sea creatures beneath the surface while just a few steps above you can enjoy a relaxing panorama tour from the deck of our semi-submarines. We offer you a choice between a smaller and a larger semi-submarine. Our classic boat with capacity of 12 people and a short, but worthwhile tour of 30 minutes gives you an opportunity to see beautiful panorama of Krk from the sea, as well as the underwater view of sea bottom and fish. The best part about it is the ability of our smaller boat to come really close to the shore and the shallow waters, so you can get the best view possible. Big Marlin tour is a 45 minute tour on the biggest semi-submarine in Croatia. First we sail to a small bay rich with fish, then we visit an underwater sculptures park and then we watch a beautiful mermaid show and sail back.
