What Kos is famous for

Hippocrates and the medical tradition

Kos is internationally famous as the birthplace of Hippocrates, around 460 BC, the physician considered the founder of modern medical science and creator of the well-known Hippocratic Oath. His name is inextricably linked to the island through monuments, museums, and place names, and every year visitors from all over the world come specifically to see the sites related to his life and work, making Kos a point of reference for the history of medicine.

The Asklepieion

A few kilometres outside the town lies the Asklepieion, one of the most significant healing and worship centres of antiquity, dedicated to the god Asclepius. Built on three successive terraces within a pine forest, it functioned as a medical school and hospital, combining treatment with worship. The ruins, with their colonnades and views extending to Asia Minor, remain among the most important archaeological complexes in the Aegean.

The Plane Tree of Hippocrates

In the main square of Kos Town, next to the castle, stands a huge plane tree which tradition claims was planted by Hippocrates himself, although its age does not historically confirm this. The tree, with its enormous trunk supported by marble columns, is a symbol of the town and a spot every visitor photographs, connecting the legend with the daily life of the market surrounding it.

The Knights' Castle

Kos is also famous for the imposing Castle of Neratzia, built by the Knights Hospitaller in the 15th century to protect the harbour from raids. The two defensive zones, the coats of arms of the Grand Masters, and the materials from ancient monuments incorporated into its walls attest to the island's historical stratification, from antiquity to the medieval era of the Knights' rule.

The endless sandy beaches

The island is renowned for its extensive sandy beaches, particularly on the southern and western sides, where beaches such as Kefalos, Paradise (Paradeisi), Mastichari, and Bros Therma offer shallow waters and organised facilities. The combination of gentle breezes in some coves and more open coasts for watersports makes Kos popular for both families and water activity enthusiasts.

Cycling as a way of life

Thanks to its relatively flat terrain, Kos is famous as one of the most cycling-friendly Greek islands, with an extensive network of cycle paths connecting the town with beaches and villages. Locals and visitors use bicycles daily for getting around, while bike rental is one of the most popular options for exploring the island without a car.

Must-see attractions

Archaeological site of the Agora

In the centre of the town, next to the harbour, extends the ancient agora site with ruins of temples, stoas, and baths from the Hellenistic and Roman periods. A stroll among columns and mosaics, with the castle as a backdrop, offers an insight into ancient urban planning and Kos's significance as a commercial hub.

Archaeological Museum of Kos

In Eleftherias Square, the museum houses finds from the Asklepieion and other sites on the island, featuring significant statues, mosaics, and inscriptions. The statue believed to be a possible depiction of Hippocrates is one of the most photographed exhibits, and a visit helps one better understand the island's historical journey.

Asfendiou and Zia

At the foot of Mount Dikaios, the mountain villages of Asfendiou and Zia retain traditional architecture, tavernas serving local produce, and small churches. Zia is particularly famous for its sunset, with many visitors ascending every evening for the view towards the Aegean and neighbouring islands.

Kastello Antimachias

The medieval Knights' castle in Antimachia, built on a plateau, offers panoramic views stretching to the airport and the sea. Within its walls, churches with frescoes survive, while its location made it a strategic point for controlling the central part of the island during the Middle Ages.

Platania and the thermal springs of Embros Therma

Next to the eponymous beach, natural hot springs mix with the sea, forming a natural warm water pool. This spot is popular in the afternoon, especially during winter months when the water temperature is more pleasant, offering a unique experience of relaxation in nature.

Local gastronomy: what to try

• Pitia Kos — Traditional cheese pie with local sour cheese (xinotyri), wrapped in filo pastry, baked or fried, a staple of local cuisine.
• Xinotyri Kos — Sour, soft cheese made from sheep's or goat's milk, with an intense flavour, used in pies and also eaten on its own.
• Kos Wine — The island has a tradition in viticulture, with local varieties producing white and red wines in many wineries in the area.
• Kremmydopita (Onion Pie) — Savoury pie with onion and local cheese, a common breakfast or mezze in traditional cafes on the island.
• Seafood of Mastichari — The fishing village of Mastichari is famous for fresh fish and seafood, served in tavernas next to the small harbour.
• Kos Honey — Thyme honey from the island's mountainous areas is considered a high-quality local product and a frequent gift for visitors.

Beaches, nature and landscape

Kefalos Beach

A large sandy beach on the south of the island, with strong winds that make it popular with watersports enthusiasts like windsurfers and kitesurfers, as well as those seeking a wilder, wind-swept beauty.

Paradise Beach (Paradeisi)

One of the most photographed beaches in Kos, with shallow turquoise waters and white sand, largely sheltered from winds, ideal for families and calm swimming.

Mount Dikaios

The mountain range traversing the island offers hiking trails among plane trees and springs, connecting the mountain villages and providing coolness and views that contrast with the coastal areas.

Alyki Lagoon

On the western side of the island, near Tigaki, the lagoon hosts flamingos and other waterfowl during migration, making it an important wetland and a point of interest for birdwatching.

When to visit

The best period to visit Kos is from mid-May to mid-October, when the sea is suitable for swimming and all facilities operate normally. July and August bring the largest crowds and highest temperatures, while June and September offer a milder climate and fewer crowds, ideal for cycling and excursions. Spring is suitable for hiking on Mount Dikaios, while in winter many businesses close and the island operates at a more local pace.

How to get there

Kos is connected by flights from Athens, Thessaloniki, and several European destinations to "Hippocrates" airport, approximately 24 kilometres from the town. By ferry, it is served by Piraeus-Dodecanese lines with a journey time of approximately 10-12 hours, while there are also high-speed ferries from Rhodes, Kalymnos, and other neighbouring islands, as well as daily routes to the Turkish coast (Bodrum), which is just a few kilometres away.

Where to stay

Kos Town suits those who want vibrancy, nightlife, and easy access to sights and the harbour. Kefalos and Kardamena offer a more youthful atmosphere with bars and concentrated entertainment, while Mastichari and Tigaki are quieter options with a family character. Mountain villages like Zia suit those who prefer a traditional atmosphere away from the coast.
