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 ).

Me and my partner had an amazing day during the tour. The guide was really kind and helpful. We enjoyed the activities a lot but could have been great to have more time to swim in each of the stop because we only had around 20 min which was very short. Other than that the tour was very good
