Ferry Piraeus → Kos 🇬🇷🇬🇷
Twelve hours at sea separate Piraeus from Kos, the third-largest island of the Dodecanese and one of the most popular for its beaches and its ancient site — the Asklepieion, where Hippocrates is said to have taught. Blue Star Ferries runs the line overnight: board in the evening at the port of Athens, arrive the next morning, leaving you the whole day on the island. Kos is also the best base for exploring the Dodecanese: Kalymnos, Nisyros and Rhodes are within catamaran range, and Turkey is only a few kilometres away. Cars and two-wheelers are carried.
