I booked just 20 minutes before. The confirmation was very quick and we were taken care of immediately. As a bonus, we saw a turtle. Thank you to the team.

Small boat, plenty of time to swim, and the skipper did his best to locate the turtles for us.

The trip is really quick, probably the fastest in the area. The skipper is calm, friendly, helpful, and chatty. Definitely a must!

Turtle Island which you can visit during the boat rental in Zakynthos with Fun@Sea.
Stefanie · CoupleGRGreece

Hello, we booked online and paid via PayPal; everything was handled extremely professionally. We were given private parking, comprehensive information, and professional instruction on the boat. We'll never forget this day. It was wonderful. Since we had no boating experience, the nine hours on the water were a fantastic experience! We were also helped again with parking in the harbor. We felt well looked after and would definitely recommend them. Thank you so much 🙏, see you next time! 👍👍👍 Five stars 🤩
