Kos is one of the friendliest big islands of the Dodecanese, and one of the easiest to reach: overnight ferries sail from Piraeus, daily connections link it with Rhodes, and very frequent boats hop across to neighbouring Kalymnos. All of them arrive at the harbour of Kos Town, right beneath the walls of Neratzia Castle. This is the birthplace of Hippocrates, and his legacy is everywhere, from the hillside Asklepieion sanctuary to the ancient plane tree where he is said to have taught. Just as memorable is how you get around: the island is largely flat, making Kos Greece's best cycling island, with easy rides out to Tigaki's long sands and Paradise beach, while the mountain village of Zia rewards the climb with famous sunsets.
Ferries berth in the harbour of Kos Town, directly below the medieval walls of Neratzia Castle and a short stroll from the Plane Tree of Hippocrates, the palm-lined waterfront and the town's cafes. Overnight ships arrive from Piraeus, daily boats connect with Rhodes, and small ferries shuttle very frequently across to Kalymnos, making the port a natural base for Dodecanese island-hopping.
Ferries from Kalymnos to Kos run multiple daily. Frequencies rise in summer and around Greek holidays and drop in winter, so always check live schedules for your travel dates.
