Where is Kos

Kos is an island in the Dodecanese archipelago in the east of Greece. It is nestled between the islands of Nisyros, Kalymnos, and Astypalea, with Tilos, Rhodes, Leros, and Symi not far away. It is also located close to the Turkish mainland, with the tourist town of Bodrum being less than 25km away from the island’s capital.

The best time to visit Kos

The best time to visit Kos is during the summer season, which runs from around May until October. Flights do sometimes start a little earlier than this (mid/end of April), but the sea and evenings are still quite cold at this time.

The spring months are best if you want mild temperatures, low prices, fewer crowds, and would like to see the wildflowers in bloom, while the latter months of September and October are best if you want to enjoy the luscious warm water.

The peak months in Kos are July and August, when temperatures are well in the 30s (sometimes 40s), prices are higher, and hotels are much busier. This is still a great option if you’re a family and need to travel in the summer holidays, but the shoulder months are preferable if you have the choice.

Kos’ famous theater, the Roman Odeon, dates back to the 2nd or 3rd century.

The first nine rows were cut from marble and were designated for royalty and members of the upper echelon of ancient society.

However, Antimachia is rumored to have been used as a prison for condemned knights. Despite the numerous attacks over many years, the outside fortifications of the castle still stand strong.

The castle’s only entrance can be found in the double gates on the north side of the fortress. Inside the church, not much remains, but you can see the two Venetian churches built in the 16th and 18th centuries.

Although the churches aren’t as old as the original structure, they do still hold services. Views from the top of the battlements include the Kardamena coast and the island of Nisyros. The Castle of Antimachia is free to visitors and open daily.
