Ann · FamilyBEBelgium "We had really value for money. The organisation is very professional. They really want to give you a very relaxed feeling, no matter how busy they are. Our boat was running late and they gave a replacement with a private boat. Thank you very much, we had a lovely afternoon!"

Luca · CoupleITItaly "The most complete tour of the southwestern part of the island, with many breaks to swim in the crystal clear waters and discover the coves. The two turtles that we were able to spot from the boat in the bay were also wonderful."
