Things to Do in Kos, Greece

Few Greek islands mix ancient ruins and easy beach days as neatly as Kos, the Dodecanese island where Hippocrates was born. We at VayCay Couple spent a week working out what earns your time, and here is our honest guide to the best things to do in Kos, Greece, with the prices, the bus numbers and the beaches we would go back to. Kos island runs about 40 km end to end but you can cross it in an hour, so you can stand among 2,000-year-old columns in the morning and swim by lunch. Most people search Kos Greece expecting only cheap resorts, and the island quietly beats that reputation. We checked prices in August 2026.

What is Kos known for?

Kos is known for two things above all, its beaches and its medicine. This is the birthplace of Hippocrates, the father of Western medicine, and the island’s headline sight is the ancient healing sanctuary named after him. Around that sit long sandy beaches, a compact harbour town, a mountain village famous for its sunset, and some of the flattest, easiest cycling in the Greek islands. It is a strong pick for a first trip to Greece, with reliable buses and plenty of English spoken.

What is worth seeing in Kos Town?

Kos Town packs the history into a walkable loop. Start at Neratzia Castle, the fifteenth-century fortress the Knights of St John raised over the harbour, then wander the free open-air Ancient Agora with its mosaic floors and toppled columns. Pause at the Plane Tree of Hippocrates, where the great physician is said to have taught, and finish at Casa Romana, a restored Roman villa with frescoes and mosaic courtyards for about 6 euro. Allow three easy hours with a coffee stop on the harbour, and the whole of Kos Town is made for a slow evening stroll.

Is the Asklepion Kos’s must-see ruin?

Yes, the Asklepion is the one unmissable ruin. It sits about 4 km southwest of Kos Town and was one of the ancient world’s great healing sanctuaries, the medical school linked to Hippocrates, laid out over three terraces of columns, baths and temples with a long view back over the town and the sea to Turkey. Entry is about 8 euro, or 4 euro reduced, and a bus runs from Kos Town every half hour in season for around 1.80 euro. There is little shade, so go early and take water. For any first-timer working out what to do in Kos, this is the anchor of the trip.

Which are the best beaches in Kos?

The best beaches in Kos are spread along the coast, so a car or scooter helps. Paradise Beach on the south coast is the famous one, soft sand with natural gas bubbles fizzing up through the shallows, and sunbeds for around 15 euro a pair. Agios Stefanos pairs swimming with the ruins of an early Christian basilica right behind the sand and the tiny islet of Kastri to paddle out to. Tigaki in the north is a long, shallow stretch backed by a salt lake where flamingos gather in spring, while Mastichari is a working fishing village with calmer water and the ferry to Kalymnos. For a free soak, Therma Beach has a hot spring that pools against the sea.

Is Zia worth the trip for sunset?

It is, as long as you plan it. Zia is a small village up in the hills above Kos Town, and its west-facing terraces give the best sunset on the island, out over the Aegean toward the neighbouring islets. Arrive by late afternoon to wander the craft and honey stalls, then book a table ahead at a sunset taverna such as Oromedon, because they fill fast the moment the light turns gold. It is the shot everyone means when they search Zia Kos, so finish with loukoumades, the honey-soaked dough balls, and drive down after dark.

How do you get to Kos and around the island?

Kos International Airport takes direct summer flights from across Europe, and sits about 23 km from Kos Town, with bus number 10 running roughly hourly for around 4 euro or a fixed taxi at about 45 euro. By sea, Blue Star ferries link Kos to Piraeus on a nine-hour overnight sailing and to Rhodes in about two hours. On the island, orange KTEL buses reach the main villages, scooters and quad bikes go from about 25 euro a day, and a flat 15 km cycle path follows the north coast for a breezy day on two wheels.

What should you eat in Kos?

Kos eats simply and well. Order goat stifado, a slow red-wine stew, or a plate of grilled souvlaki at a long-running Kos Town taverna such as Taverna Mike, where a main runs about 12 to 16 euro and a gyros wrap is nearer 4. Local honey, thyme and soft cheeses turn up on every meze table, and the island makes a decent white wine. For the wider picture of Greek food, the dishes here overlap with neighbouring Rhodes.

Kos at a glance

What time of year suits Kos best?

May, June and September into early October are the sweet spot, with warm days, a sea around 22 to 24 degrees and far thinner crowds than midsummer. High summer is hot and brings the Meltemi wind to the north coast, so if you are chasing calm water in August, choose the sheltered south and west around Kefalos. Many Kardamena bars wind down by mid-October, but hotels discount heavily and the ruins are far more pleasant to walk.

Ferry timetables and festival dates shift through the season, so the national tourism site Visit Greece keeps the current details.
