Ferry Athens (Piraeus) → Kos 🇬🇷🇬🇷
The ferry from Athens (Piraeus) to Kos links mainland Greece with one of the largest islands of the Dodecanese, deep in the southeastern Aegean. Blue Star Ferries operates this long-haul route with conventional vessels such as the Blue Star 2, typically as an overnight crossing of around 11 h 40 that lets you sleep on board and wake up at the island. Kos is famous as the birthplace of Hippocrates, with vast sandy beaches, Roman ruins, a medieval Knights' castle and an easy, flat landscape made for cycling. Because it is a port of call on a Dodecanese line, departures run several times a week through the summer rather than daily, so booking ahead is worthwhile.
