Kos

What Kos actually is

Kos is a long thin island in the Dodecanese, about 40 kilometres end to end and rarely more than 8 kilometres wide, lying so close to the Turkish coast that from the town waterfront you are looking at the hills behind Bodrum rather than at open sea. It is the third biggest island in the group after Rhodes and Karpathos, and it is the only well-known Greek island that is genuinely flat.

That flatness is the single most useful fact about the place. Most Greek islands are a mountain with a coastline attached, and getting from your hotel to a shop involves a hill and a moped. Kos has a coastal plain running along its northern side, a dedicated network of cycle paths around and out of the town, and rental bikes at a price that makes taxis look silly. Families who would never cycle on Rhodes or Crete do it here without thinking about it. The island only really rises at Mount Dikeos in the middle, which tops out at 846 metres and holds the mountain villages.

The second thing to understand is that Kos has genuine ancient depth, and it is not tucked away in a museum somewhere. Hippocrates was born here around 460 BC, the Asklepion healing sanctuary above the town was one of the most important in the Greek world, and the town centre itself is dug through with Roman and Hellenistic remains that you walk past on the way to dinner. A 1933 earthquake flattened much of the town, and the Italian administration of the day used the rebuild to excavate what was underneath. That is why the ruins are so exposed and so central.

Kos Town: the ruins, the castle and the bikes

Kos Town is where about half the island's visitors stay and it is a good default. The harbour is guarded by the Neratzia castle, built by the Knights of St John and connected to the town by a bridge over what used to be a moat. Beside it stands the plane tree that guides will tell you Hippocrates taught under; it is old, it is not that old, and the story is worth hearing anyway.

Walk five minutes and you are in the western archaeological zone: a Roman odeon, a gymnasium colonnade, mosaic floors under shelters, and the Casa Romana, a reconstructed Roman villa that is genuinely worth the ticket. None of this needs an excursion. It is a stroll.

The town beach is average — Lambi to the north is better — but nobody stays in town for the beach. You stay for the restaurants, the flat streets, the bike hire and the fact that the ferry quay is right there.

The Asklepion, and why it is not just another ruin

Four kilometres uphill from the town, on three terraces cut into a slope with a view straight across to Turkey, sits the Asklepion. This was a working medical sanctuary from the fourth century BC, associated with the school of Hippocrates, where treatment mixed genuine observation with temple ritual. There are baths, a temple platform, and a monumental staircase that pays back the climb.

Go early or late. The site is exposed and there is almost no shade, which in July is not a small detail. It is 25 minutes on a bike from town along a marked route, and the little tourist train also runs there.

Where to stay: the family end, the party end and the wind

Tigaki and Marmari

Ten to fifteen kilometres west of town on the north coast. Long, pale, sandy beaches that shelve very slowly, which is exactly what parents of three-year-olds want and exactly what serious swimmers find tedious. Behind Tigaki is the Alykes salt lake, which holds flamingos in spring and autumn. Both places are quiet, low-rise and full of half-board family hotels. The north coast catches the meltemi, so on windy afternoons in July and August expect chop and a lot of kitesurfers.

Mastichari

The other family option, further west and smaller, with a genuine village centre, a wide beach and the ferry quay for Kalymnos. It suits people who want a low-key week with somewhere to eat that is not a hotel buffet. It is close to the airport, which cuts both ways: short transfer, occasional aircraft noise.

Kardamena

The party end, and it is honest about it. Kardamena on the south coast is a resort of bars, clubs and cheap food aimed at a young British and northern European crowd, busiest from June to early September. It also happens to have a good long beach and the ferry to the volcano on Nisyros. If you are twenty-two and that is the holiday, it works. If you have children or you go to bed before two in the morning, book somewhere else — the difference between Kardamena and Mastichari is not a matter of taste, it is a matter of decibels.

Kefalos and the south-west

The far end of the island, around Kefalos bay and Agios Stefanos with its ruined basilicas and the little Kastri islet with a chapel on it. This is the most scenic corner and the beaches — Paradise, Camel, Magic — are the best on Kos. It is also 40 kilometres from town and windier than the north, and the hotels are mostly big all-inclusive resorts on the hillside above the bay. Choose it for the views and the water, not for walking to a taverna.

Zia and the mountain villages

Nobody stays up here, but everybody should go once. Zia sits on the flank of Mount Dikeos and is the sunset spot, which means coaches. Go for an early dinner rather than the sunset crush, or walk part of the way up to Old Pyli, where a Byzantine ruin sits over the plain with nobody in it.

Hotel stock and what your money buys

Kos is a package island and the stock reflects that: a lot of four-star all-inclusive and half-board hotels built for northern European charter traffic, a smaller layer of five-stars at Kefalos and around Psalidi east of town, and a growing set of small boutique places inside Kos Town itself.

The 58 EUR per person per night anchor is a shoulder-month figure for a good four-star near town or Tigaki with half board. All-inclusive here is worth considering more than on many Greek islands, because the resort areas outside town are genuinely thin on restaurants — in Kefalos or on the Psalidi strip you will eat in the hotel most nights whether or not you planned to. In Kos Town or Mastichari the reverse is true and bed-and-breakfast usually gives better value.

Getting there, and the Bodrum question

Kos International Airport, code KGS, sits in the middle of the island near Antimachia, about 24 kilometres from Kos Town — roughly half an hour — and much closer to Mastichari and Kardamena. Charter and low-cost flights run from most of northern Europe between late April and October, and connections thin dramatically in winter.

For Turkish readers the ferry is the real story. Kos Town harbour faces Bodrum across roughly 20 nautical miles and the catamaran crossing takes somewhere between twenty and fifty minutes depending on the boat, with several sailings a day in summer and a much thinner winter timetable. It makes Kos a day trip from Bodrum, and equally makes Bodrum a day trip from Kos.

There is a caveat and it matters. Greece is in the Schengen area, so a visa is required for Turkish passport holders. A separate scheme has been running for several seasons that allows a short on-the-door visa for a specific list of eastern Aegean islands, and Kos has been on that list. The terms and the fee have changed more than once, so treat it as something to verify against the current official announcement before you buy tickets rather than as a fixed rule.

One thing we will not blur: we quote accommodation only here. Any transfer, ferry ticket or car hire on Kos is arranged locally. Our own vehicles and drivers have run airport transfers in Turkey since 2016, and that is the only country where we drive.

Cycling, properly

This is the section that sells Kos to people who did not think they wanted it. Kos Town has a network of separated bike lanes running several kilometres along the seafront and out to the Asklepion turn, and the coastal road west towards Tigaki is flat and manageable for a normal person on a hired town bike.

Rental is cheap and available everywhere, hotels lend bikes, and the distances are sane: town to Lambi is fifteen minutes, town to the Asklepion twenty-five, town to Tigaki around an hour at a gentle pace. In July and August ride early — the heat, not the terrain, is what stops people.

When to go

May is lovely and cheap: green, mild, sea around 19 or 20 degrees so swimming is for the brave.

June is the best all-round month. Warm sea, everything open, prices below peak, and the meltemi has usually not settled in.

July and August are hot, busy and expensive. The meltemi blows hardest now — it takes the edge off the heat but flattens umbrellas on the north coast and cancels small boats.

September is arguably the best of all. The sea is at its warmest, the crowds drop sharply after the first week and the light is better.

October works to about the middle of the month. November to April is a quiet local island with most resort hotels closed and very few flights.

Who should skip Kos

If you want dramatic mountain scenery and dizzying coastal roads, this is the wrong island — Kos is deliberately gentle, and Rhodes, Crete or Karpathos will serve you better. If you hate wind, the north coast in high summer will annoy you. If you are looking for an unspoilt Greek village experience, remember this is a charter island and the coast reflects that; the mountain villages are the antidote but you will need transport. And if you are travelling with children, do not book Kardamena on price alone.

Getting a real price

The gap between a June half-board room near Tigaki and an August all-inclusive week at Kefalos is wide, and the right answer depends on whether you want to walk to dinner or not. Send us your dates, the number of travellers and the ages of any children, and say whether all-inclusive matters or whether you would rather be somewhere with restaurants outside the hotel. A consultant replies within one working day with two or three properties and honest reasoning for each. The quote is free and commits you to nothing, and no payment is taken on this site — if you accept, you pay the partner agency that issues the booking and the voucher, and that agency is named before you decide.
