About Kos: The Island of Hippocrates
Kos, the third most popular island in Greece's Dodecanese group, stands out with its historical and cultural richness. Located directly opposite the Bodrum Peninsula, the island has been an important center for trade, culture, and healing since ancient times. The island's greatest source of pride is undoubtedly that Hippocrates (460 BC - 370 BC), considered the founder of modern medicine, was born and lived here. Hippocrates' philosophy and contributions to medical science are felt in every corner of the island.
Throughout history, Kos has been home to many different civilizations. Ancient Greek, Roman, Byzantine, Knights of Saint John, Ottoman Empire, and Italian rule have left deep marks on the island's architectural and cultural fabric. Today, as you wander through the streets of Kos, you can see ancient Greek columns on one side, a magnificent knight's castle on the other, and an elegant Ottoman mosque just ahead, all in the same frame. This multicultural structure places Kos in a special and unique position among the Greek Islands.

Asklepion and the Plane Tree of Hippocrates
Undoubtedly, Asklepion is at the top of the list of things to do in Kos. Located on a pine-covered hill approximately 4 kilometers from the city center, Asklepion is one of the most famous health, healing, and medical centers of antiquity. This temple complex, dedicated to Asclepius, the God of Health, was considered one of the most respected hospitals of its time, along with the Pergamon Asklepion in Anatolia. The massive complex, built on three different terraces, consists of rooms where patients were treated, temples, baths, and educational areas. The panoramic view of the Aegean Sea and the Anatolian coast from the top terrace is simply breathtaking.
Located very close to the harbor in the city center, the Plane Tree of Hippocrates (Platanos) is another symbol of the island. According to legend, Hippocrates taught his students medicine under the shade of this colossal plane tree. Although the current tree is believed to be approximately 500 years old and to have grown from a sprout of the original tree, it is considered one of the oldest plane trees in the world. Its enormous branches are currently supported by metal scaffolding, and the area around it is protected. The historic fountain right next to it and the charming cafes in the vicinity offer a wonderful atmosphere to relax at this historical spot.
Kos Castle and Ancient City
As you approach Kos Harbor by ferry, the first structure to greet you will be the imposing Kos Castle (Neratzia Castle). Built in the 14th century by the Knights of Saint John, this massive castle was constructed to protect the island from pirate attacks and Ottoman raids. Stones and columns from ancient structures were used in the castle's construction; therefore, if you examine the castle walls carefully, you can see ancient reliefs and inscriptions. Surrounded by a deep moat, the castle is entered via a stone bridge. Watching the view of the harbor and the Aegean from the ramparts is quite enjoyable.
Kos town center is like a giant open-air museum. The Ancient Agora (Marketplace), located in the heart of the city, dates back to the 4th century BC and is one of the largest agoras of its time. As you walk among the colonnaded streets, temple ruins, and traces of ancient shops, you can lose yourself in the depths of history. Another important structure in the city is the Roman Odeon. This ancient theater, built in the 2nd century AD, now hosts various concerts and cultural events during the summer months in its restored form. Additionally, Casa Romana, a luxurious 36-room Roman-era villa, showcases the opulent lifestyle of the period with its magnificent floor mosaics and inner courtyards (atrium).
Ottoman-Turkish Heritage
Kos Island still strongly bears the traces of nearly 400 years of Ottoman rule. There are numerous mosques, fountains, and hammams on the island. Located in Eleftherias (Freedom) Square, Defterdar Mosque is one of the city's most important symbols with its elegant minaret and architecture. Although unfortunately damaged in recent earthquakes, it maintains its historical significance in the square's silhouette.
The Gazi Hasan Pasha Mosque (Lonca Mosque), located right next to the Plane Tree of Hippocrates, was built in 1786 and is one of the finest examples of Ottoman architecture on the island. The mosque, notable for its two-story structure and shops on the ground floor, is currently closed for worship but attracts photography enthusiasts with its architectural elegance. Furthermore, the historic Ottoman Bath in the city center and old Turkish houses scattered throughout the island are elements that reinforce Kos's multicultural identity. In the cafes and restaurants run by Turkish-origin citizens still living on the island, you can find familiar flavors and warm conversations.
Kos Beaches (Tigaki, Paradise, Kefalos)
Kos is famous not only for its history but also for its crystal-clear waters and miles of beaches. The beaches in different parts of the island offer a variety to suit every type of holidaymaker.
- Tigaki Beach: Located approximately 11 km from the city center, Tigaki is ideal for families with children, thanks to its fine white sand and shallow sea. It also has suitable winds for water sports like windsurfing and kitesurfing.
- Paradise (Bubble) Beach: One of the island's most famous beaches. This beach, near the Kefalos area, is famous for the natural air bubbles (bubble) that emerge from the water due to volcanic activity on the seabed. With its fine sand and turquoise waters, it truly resembles a tropical island.
- Mastichari: The beach of Mastichari, a small fishing village, is known for its pristine white sand and wonderful sunset views. Additionally, ferry services to the island of Kalymnos are operated from here.
- Kefalos - Kamari: Kefalos bay, located at the southwestern tip of the island, stands out with its cool waters and magnificent scenery. While swimming from Kamari beach, Kastri Island and the small church on it, which you will see opposite you, form one of Kos's most iconic photo opportunities.
Popular Kos Beaches Feature Table
| Beach Name | Location | Sea/Sand Feature | Suitable For? |
|---|---|---|---|
| Tigaki | North Coast (11 km from Center) | Fine sand, shallow and calm | Families with children, surfers |
| Paradise | Southwest (Kefalos Road) | Golden sand, volcanic bubbles | Those seeking fun, young people |
| Mastichari | Northwest Coast | White sand, cool water | Those seeking tranquility, couples |
| Kamari (Kefalos) | Southwest Tip | Mixed pebble-sand, crystal clear and cool | Nature lovers, photographers |
Zia Village and Therma
Beyond sea and historical tourism, Kos's inland areas also hold beauties worth discovering. Zia Village, nestled at the foothills of Mount Dikeos, is one of the island's highest settlements. This charming mountain village, reached by passing through lush green forests, is a true Aegean dream with its traditional blue-and-white Greek houses, narrow stone streets, and authentic souvenir shops. However, what truly makes Zia famous is its unique sunset view. Taking a seat at one of the village's tavernas with a view in the late afternoon and watching the sun slowly set over the Aegean Sea and neighboring islands will be one of the most unforgettable moments of your Kos trip.
Located at the southeastern tip of the island, Therma (Agios Fokas) Beach offers a completely different experience. In this area, situated at the foot of steep cliffs, hot sulfurous waters originating from the mountain meet the sea directly. In this area, where a natural pool is formed by rocks at the seaside, you can feel the cool waves of the sea on one side while experiencing the relaxing effect of the hot water on the other. Especially in the evenings or on slightly cooler days, enjoying a natural spa at Therma is one of the most unique activities the island offers.
Kos by Bicycle
Kos rightfully holds the reputation as the "Bicycle Island" among the Greek islands. The relatively flat topography of the island's eastern and northern parts has made cycling the most ideal means of transport and exploration for both locals and tourists. There are wide and safe cycling paths extending for kilometers along the coastline, starting from the city center.
Renting a bicycle in the early hours of the day or in the cool late afternoon and cycling under the shade of palm trees, breathing in the scent of the sea, is an immense pleasure. The route extending from the city center to Tigaki beach is very popular among cycling enthusiasts. You can rent city bikes, mountain bikes, or electric bikes at very affordable daily rates from rental shops all over the island.
Kos Cuisine
Offering the most exquisite examples of Greek and Mediterranean cuisine, Kos is a paradise for gastronomy enthusiasts. The island's fertile lands and abundant seafood form the foundation of its local cuisine. Among the unique flavors of Kos, Krasotyri (wine cheese) stands out. This goat cheese, aged in red wine sediment, is indispensable for mezes with its distinctive aroma and color. Additionally, Pligouri, a dish prepared with fine bulgur, tomatoes, and local spices, is also one of the island's traditional delicacies.
The island's famous honey and figs are widely used in desserts and breakfasts. In the traditional tavernas along the coast, you must try classics like fresh seafood, calamari, grilled octopus, and shrimp saganaki, caught daily from the cool waters of the Aegean. You can enjoy Aegean evenings with local Kos wines or the traditional Greek drink ouzo to accompany your meals.
Transportation on the Island
Transportation on Kos Island is quite comfortable and varied. For public transport, KTEL buses provide regular services to almost every point on the island and popular beaches. These buses, departing from the city center, are a budget-friendly transportation alternative. If you want to plan a more free and flexible route, renting a car or ATV is an excellent option. Renting a vehicle provides great convenience, especially for reaching distant parts of the island like Kefalos or exploring the villages on the slopes of Mount Dikeos. For short distances, as mentioned before, cycling is the most pleasant and eco-friendly solution.
