Our favourite outing around Dubrovnik - Great family outing. The captain and his assistant were adorable as well as the rest of the passengers! Good Mood in music (+ drinks!). Beautiful discovery of Dubrovnik and its surroundings by boat and swimming in the famous caves (blue cellars). Our advice for this out-of-season trip: the neoprene shorty to stay longer in the water even if at apparently 20°C, it remains quite swimmable.

Fun trip - The boat took us to swim at two different cave locations- the Blue cave was particularly impressive. We then spent time at the island of Lopud which was nice to explore. The boat itself was fast and fun, and the crew looked after us well.

A fun day on the water. - This tour did a good job of fulfilling its goal of bringing you down the Croatian coast to swim into two sets of caves, and allowing time to relax on a nice beach where you can get food and beverages. The tour leaves exactly where it describes - use Google maps - and leaves right on time. There is a Marinero Tours rep at a booth by the piers who will check you in and tell you which boat you're on. Our guides onboard were Vinnie and Mario, and they did a great job of explaining what we were going to do, swimming along with us as we went to the caves, handing out beverages, and equipping guests with masks / snorkels / flotation noodles. I will admit up front that I thought this cruise was going to involve more pleasant cruising in the boat than it did. The focus of the boats is to move you at speed down the coast to the caves and beach, and provide a stable platform for moving on/off the boat to do snorkeling. Expect some water spray if you're sitting on the back of the boat. The boat had both inside and outside seating, and was quite roomy. It also had a small bathroom where you could change. In summary: Vinnie and Mario were great guides and did a great job of taking care of the guests. The tour does exactly what it describes, and it was a fun day. If you're not planning to go in the water, I won't recommend this tour - you'll be bored.

The highlight of our trip! - We had the most amazing time - definitely the highlight of our trip! Karolina and Alex were fantastic, professional but friendly and looked after us brilliantly. I'm not even a fan of caves but the boat trip and swimming is great on its own, although I did venture into the last cave for a few minutes just for the experience. We booked at the port the day before. There were 14 of us on the boat which was the perfect amount and all got chatting. Beers water and cold drinks were included. We took our own lunch and popped it in their cooler box on board. Snorkels and goggles are provided as well as pool noodles. It is a swimming trip and you need to be able to swim to get to the island where you get a sunlounger and umbrella if you buy a beer or cocktail. We had the best time and can't recommend this enough! Thank you Karolina and Alex for giving us the best day!
