Daily life
Kos is the third-largest island in the Dodecanese after Rhodes and Karpathos, with a population of 37,089 at the 2021 census — the second most populous island in the chain after Rhodes. Kos town, the administration seat, is where daily life concentrates: narrow lanes around the harbour weave past ancient agora ruins and the walls of Nerantzia Castle, built by the Knights Hospitaller in 1315. In the town square stands the Plane Tree of Hippocrates, said to be around five centuries old and named for the physician thought to have been born on the island; the nearby ruins of the ancient Asklepieion carry that medical heritage forward. Much of the town's fabric was rebuilt after the severe earthquake of 23 April 1933, and traces of the Italian period (1912-1943) still show in the architecture. Inland, vineyards, almond and fig orchards, and watermelon fields stretch across the countryside — cos lettuce, the romaine variety, takes its name from the island. Summer life gathers around the beaches, since tourism is now the main livelihood, though villages further from the coast still work olive groves and tomato fields. The island's relatively flat terrain makes cycling a natural, everyday way to get around.
Transport
The main gateway is Kos International Airport (KGS). Ferries run daily to Piraeus (Athens), with frequent sailings — often several times a day in summer — to Rhodes, Patmos, Leros and Kalymnos. Connections to Santorini, Syros and Astypalaia are seasonal and less frequent, sometimes just a few sailings a week depending on the operator. Year-round ferries connect to Bodrum on the opposite Turkish coast; the crossing takes roughly 20-30 minutes, though schedules and fares vary by operator and season, so it is worth checking current times before travelling. On the island, a bus network links the main towns, with airport buses to Kos town and Kefalos. Roads are generally paved and in good condition, which makes renting a scooter, ATV or small car a common option; the flat terrain also makes cycling an easy way to get around.

FAQ
What is the easiest way to reach Kos from Turkey?
Kos sits just across the water from Bodrum, so the most practical route from Turkey is by ferry; year-round services complete the crossing in roughly 20-30 minutes, with more sailings added in summer. Fares and timetables vary by operator and season, so it is worth checking the current schedule before you travel. Travellers arriving by air use Kos International Airport (KGS), which has connections to Athens and several European cities.
Do you need to rent a car to get around Kos?
Not necessarily; an island-wide bus network connects the main towns, and airport buses run to both Kos town and Kefalos. That said, the island's relatively flat terrain and well-maintained roads make renting a scooter, bicycle or small car an easy option too, especially if you want to reach beaches or villages on your own schedule rather than around bus timetables.
Where should history-minded visitors head in Kos town?
In the centre of Kos town, the Plane Tree of Hippocrates, said to be roughly five centuries old, stands right beside Nerantzia Castle, which the Knights Hospitaller built in 1315 to guard the harbour entrance. A short walk further leads to the ruins of the ancient Asklepieion medical sanctuary and the remains of the town's ancient marketplace, so a single walk can take in both the island's Hippocratic heritage and its Knights-era fortifications.
