We start from Kalamaki in Athens, also our final destination, and we sail south in the Saronic Gulf until Cape Sounio. Then we visit the islands Kithnos, Sifnos and Serifos in Cyclades. Finaly, we turn north-west to Ydra with final port of call Poros. The survey areas are in close proximity from the ports of call, allowing a perfect combination of performing marine biology research and visiting the most picturesque places of the Western Aegean.
