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 🤩"

Steven · CoupleGBUnited Kingdom "Pick up from our hotel by a very polite and welcoming driver! amazing tour, we had an Amazing time. we saw a turtle within 15mins of the tour, the caption was good fun which is always a bonus! The swim spot at the caves was lovely time to get amazing photos and have a once in a life time swim! Only down point at this point is the swim time Could have been longer. After this 1 hour stop at turtles island was amazing see what you can and swim around don’t sun bath you can do that at any time on your holiday! After his we went to light house restaurant for lunch at he food here is good! If your happy to spend an extra €60 for 2 of you (I would recommend you try the food) the photos you can get here are amazing! After this the olive oil museum was a refreshing last part of the tour! Lots to taste and try we would recommend the body milk! As they say in England Makes your skin feel like a baby’s bum!"
