Full description

While there was a bit of a delay with getting on the boat not the drivers fault, once on the boat we had a fabulous time. Plenty of opportunities to swim, we got to see a turtle and the driver was careful to not get too close. I thought it was a great day.

Had to wait a long time for the bus. However, being on the water in a small speed boat with captain Angelo fully made up for it - we even got to swim in one of the caves. The olive factory was also quite interesting. All in all very good value for money (and we spotted a lonely turtle in the end ).

It clearly exceeded our expectations. We were picked up from the hotel on time. Chilled bottles of water awaited us on the bus for free. At our first stop we looked at turtle nests with our guide Sakis from Dalí-Tours and learned a lot of information about the Caretta turtle. After that we went to the glass bottom boat, where we were able to take sensational pictures of a turtle. Then we went on to the Keri caves. There we made a stop for swimming and dived through one of the caves. Diving goggles are a must to see the beautiful crystal blue sea water from below. After swimming, we continued to Marathonisi, the infamous Turtle Island. There we had the opportunity to have a small snack, which was sold on site. The olive oil museum afterwards was unplanned, but extremely interesting. We also had the opportunity to taste and buy various olive oil products.
