The swim at Aspi Amnos was unforgettable. The stop in Othonoi with a swim in the very warm water on the beach in front of the village. The boat is large and can carry a lot of people, but it is perhaps also for wintertime. It is hot and there is no space for sunbathing. I would remove the stop at Manthraki in exchange for another swim at the beaches of this small island. Diablo was also beautiful. It was not possible to see the Calypso Cave in Othonoi because other boats were moored there. Overall, a beautiful trip.

Of the whole tour, only the third stop was somewhat worth it, and the fourth stop was mediocre... the rest was mediocre.

Throughout the entire boat tour, we were constantly bothered by the diesel fumes from the boat. Several of our family members were nauseous from it all day. The first stop was unnecessary for us; it was nothing special. The second stop at the beach was wonderful. After that, we ate and swam on Othoni. The 55-minute return trip was again filled with diesel fumes, resulting in headaches and nausea. In summary, I would not recommend this boat trip to others.
