Full description

Marvel at the works of nature as you sail through blue waters on this boat cruise. Explore various islands and get the chance to see exotic and protected species.

After being picked up from your accommodation, begin your cruise from the port of Agios Sostis. From there, sail south with your guide to the stunning Keri Caves, where you will be given fantastic photo opportunities.

The trip was delayed due to traffic chaos and buses that could not arrive. Too many tourists Couldn't hear the guide because of the noise on the boat. The surroundings were beautiful and good time for bathing

Brilliant day out

Very well organized tour, a lot of seriousness… maybe too much! We were able to see only one turtle, on the other hand a visit to the caves (swimming among the fish in the turquoise water) "Made my day";)
