It was really good. They didn't follow the itinerary on point, but we had 3 swimming stops and we went to the shipwreck and blue caves so they delivered on what was promised.

Stefano · FamilyITItaly

Traventure Zakynthos: Extremely efficient service and extremely friendly staff. We booked the night before for four people (2 adults and 2 children). We checked in the morning. The girl was clear and kind, and the boat operator was very kind to us and the children, whom he involved in the trip (much appreciated). The return trip can be booked by calling 30 minutes in advance, but they were ready within 15 minutes. The return trip was also very friendly and prompt. Highly recommended! Checkyeti: First time, it worked great.

Captain Alexandros was a fantastic and very entertaining tour guide. This tour far exceeded our expectations. We were very surprised that no one else gave the crew any tips...

Great tour at the end of September, although most of the turtles were already migrating, we were able to marvel at one. The swim stops were wonderful.
