Getting around

Kos International Airport sits mid-island, about 25 minutes from Kos Town. Buses connect the main resorts and beaches but thin out in the evening and shoulder season. The island is famously flat, so bicycles handle Kos Town and nearby beaches easily on dedicated paths, while a rental car or scooter is best for Kefalos, Zia and the south coast. Ferries and catamarans link Rhodes, Kalymnos, Nisyros and Bodrum in Turkey.

Safety

Kos is safe with very low crime, and the main issues are sunburn, dehydration and scooter accidents on gravel-edged roads. Some beaches have strong afternoon winds and undertow, especially on the exposed south and west coasts. Sea urchins are common on rocky entries. If day-tripping to Bodrum, carry your passport and check visa rules for your nationality before booking.

Frequently asked questions

How many days do you need in Kos?

Five to seven days is ideal. One day covers Kos Town's ruins and castle, one the Asklepion and Therma springs, two or three for the beaches at Tigaki, Paradise and Kefalos, one for Zia and the mountain villages, and one for a boat trip to Nisyros, Kalymnos or Bodrum.

What is Kos best known for?

Kos is known as the birthplace of Hippocrates, with the Asklepion healing sanctuary above town, and for having some of the longest sandy beaches in the Dodecanese. It is also unusually flat, which makes it Greece's most cycle-friendly island, and it has Roman, Byzantine and Knights of St John ruins scattered through the modern town.

When is the best time to visit Kos?

May, June and September bring warm sea, open tavernas and manageable crowds. July and August are hot and busy with package holidaymakers, though the meltemi wind keeps evenings bearable. October still swims comfortably, while November to March sees most resorts shut and ferry links reduced.

Which are the best beaches in Kos?

Tigaki and Marmari have long shallow sand ideal for families, Paradise Beach on the south coast is the postcard bay with bubbling seabed springs, Agios Stefanos pairs sand with basilica ruins and Kastri islet, and Kefalos Bay suits windsurfers. Lambi and Psalidi are cyclable from Kos Town for a quick swim.

Can you do a day trip from Kos to Bodrum, Turkey?

Yes, catamarans cross to Bodrum in about 20 to 45 minutes, usually with morning departures and late-afternoon returns in season. Bring your passport, arrive at the port early for check-in, and check whether your nationality needs a Turkish e-visa. Bad weather occasionally cancels sailings, so keep the trip away from your flight home.

Do you need a car in Kos?

Not if you stay in Kos Town, where bikes and buses reach the nearest beaches on flat dedicated paths. A car or scooter is worth two or three days to see Zia, Kefalos, Limnionas and the Palio Pyli ruins, which buses serve poorly. Book ahead in August when rentals sell out.

Is Kos expensive?

Kos is one of the better-value Greek islands thanks to its package-holiday infrastructure. Budget around $90 to $160 a day for mid-range travel with a hotel, tavernas and some car hire. Prices peak in August, while May, June and late September deliver the same beaches at noticeably lower rates.
