Kos, the third island in the Dodecanese, after Rhodes and Karpathos, is second only to Rhodes when it comes to population. It belongs to the South Aegean region and is one of the most popular holiday resorts in Greece among Europeans.

With more than a hundred kilometers of coastline, Kos is ideal for a beach vacation. It has fairly rugged geography, featuring several capes with romantic landscapes of the sea.

Other than the main village, Kos Town, there are several interesting settlements worth a visit on the island, including Kardamena, Antimakia, Mastichari, and Kefalos.

Besides the attractive beaches, Kos is famous for its lively nightlife and rich history. There are several remarkable archaeological sites to visit and ancient ruins and castles to admire.

Those travelers who can’t stay still and enjoy moving from one place to the other when they are on holiday can easily cross the border and reach the touristic resort of Bodrum, in Turkey, leaving from the port in Kos Town.

A visit to Bodrum can be a fantastic day trip experience as well as an optional two-country holiday if you wish to combine a visit to Greece and Turkey during the same trip.

Let’s now dive into this Kos Island guide to discover everything about it.

Since Kos remains one of the most visited destinations in the Dodecanese, traveling to the island is not difficult.

How To Travel To Kos By Plane

Kos is home to Hippocrates International Airport, receiving flights from Athens all year round; the trip lasts about an hour. Although less frequent, the island also gets flights from Thessaloniki, Heraklion (Crete), Rhodes, and the small island of Astypaleia.

From May to September, several international flights and charter flights reach Kos from Europe in summer. Since the airport is about 25 km from the main town, booking a rental car in advance or even a taxi for transfer services is always a good idea.

How To Travel To Kos By Ferry

Easy to reach by sea as well, there are ferries from the port of Piraeus (in Athens) several times a week, the trip is quite long though (about 12 hours).

It is also possible to reach Kos by ferry from the ports of the following nearby islands: Rhodes, Leros, and Kalymnos.

Often described as the perfect destination for all-inclusive holidays, the island is an excellent place for those who look to check in a hotel and do virtually nothing during their time over there. However, this would be an unforgivable sin, there is a lot to see, explore and do on Kos, and it would be really a pity to miss it.

When visiting Kos, it’s a great idea to devote time to visiting the imposing archaeological sites that the island is known for. Don’t miss a stop at the ancient castle that protects the port in Kos Town, as well as the Italian Forum, Hippocrates Tree, or the Ottoman fountains and mosques.

The island is blessed with abundant water resources all year-round; therefore, you will find a much greener landscape that you can see in the rest of the Dodecanese.

If you are a fan of sports, Kos offers plenty of opportunities to practice windsurfing; in fact, there are windsurfing centers on many of Kos’ beaches where you can even learn how to windsurf or even rent the necessary equipment.

Kefalos and Mastichari are the best places for windsurfing on the island. Another popular activity is diving, there are several uninhabited islets and interesting old wrecks to discover, so you can either venture on your own or join one of the many organized trips offered on different beaches.

Visit The Old Town

This is undoubtedly the most visited and active part of the city, with plenty of souvenir shops, tavernas, bars, and restaurants. However, it is also a great place to learn about its history. One of the few on the island that survived a powerful quake back in 1933, this ancient area features the Italian market, several squares, and a fascinating ancient Turkish fountain.

The Castle Of The Knights

If you’re visiting Kos with children, you will share their fascination during a visit to the Castle of the Knights of Saint John, also known as Nerantzias. It features very ancient walls made of local stone and several blazons and columns that belong to the ruins of the old town.

This imposing building dated back to the occupation of the Knights, dating back to approximately 1450, and that lasted for two centuries. This impressive two-precinct castle still features towers, gun ports, and bastions, as well as unique gates, bridges, and dungeons.

Inside the castle, it is also possible to visit the museum, located in the formers warehouse of the castle, inside you will appreciate exhibits such as several sculptures and ancient inscriptions.

Hippocrates Plane Tree

You cannot say to have been to Kos if you don’t get back home with a selfie taken by the tree of Hippocrates!

The plane tree of Hippocrates is located right in front of the Castle of the Knights, and it is a famous spot on the island since it is said that Hippocrates used to sit under its shade to teach his pupils. The truth is that the tree is barely only 500 years old; therefore quite impossible for Hippocrates to have sat there since he lived in the fifth century BC.

But don’t be disappointed, because you will still find something quite rare; this monumental tree has a 12-meter perimeter, and is surrounded by some beautiful historic walls with inscriptions in Arabic on it, a memory of the Turkish occupation of the island.

Archaeological Museum of Kos

Located in a building of clear Italian origins, the museum of Kos is a great place to admire ancient statues and mosaics. The most important objects that the museum exhibits is a statue of Hippocrates and a magnificent mosaic depicting Hippocrates and Asclepius.

Check The Ancient Agora Of Kos

Situated behind the area of Kos main harbor, in Kos Town, the Ancient Agora of Kos is a huge area dating back to 366 AC.

Unfortunately, due to the different quakes that hit the island over the centuries, the whole excavation area has several findings in ruins; however, there are many architectural findings, a shrine dedicated to Aphrodite, old columns, and arches. Since the Agora is surrounded by a fantastic green park with palm trees, it can be a perfect sightseeing opportunity for the whole family.

Explore The Aesclepieion

Arguably the most remarkable archaeological site to visit on the island, located about 4 km from Kos Town, the Aesclepieion is an antique site believed to be a medical center of the classic period. Dating back to the III century BC, the temple was built in honor of Asklepios, the Greek god of health and medicine.

The sanctuary features different rooms devoted to healing and therapy. It has a terrace with a portico, which is believed to be the place where stood a prestigious ancient medical school.

There are also Roman baths (from the III century BC) and several spaces for patients and families inside the building. There is also a second terrace that holds an ancient altar and some restored columns from an older Greek temple dedicated to Apollo that used to be in the area. There is also a Doric temple and an old church built during the Christian period on the last terrace.

Enjoy A Visit To The Mosque Of Nefterdar And Hanji Hasan Mosque

You will find this Ottoman building in Eleftherias Square, in Kos Town. The mosque dates back to the end of the eighteenth century and is one of the most classic examples of Islamic architecture in the whole country.

Another beautiful Turkish monument is Hanji Hasan Mosque, a two-floor building that boasts a beautiful minaret. The religious building dates back to 1786, and it is only steps from the plane tree of Hippocrates.
