If you have an appreciation for history, architecture and natural beauty, there are many sites on the island that you should make time to visit. The famous Asclepeion is the largest healing centre in the ancient world and is located on the slopes of the hill with a magnificent view of the coast. Neratzia, a medieval fortress, again offers amazing views of the sea and is situated at the eastern end of the harbour.
Explore Palio Pyli, an abandoned medieval village built on the slopes of Mount Dikeos or the Byzantine Castle to view more stunning views of Kos. If you visit the Mount at sunset, you will experience views of the Turkish coast which would be hard to beat.
If swimming is more your thing, Therma has a thermal pool with hot springs and a black pebble beach which is worth a visit. The beaches of Kardamena, Tigaki and Mastihari are some of the most popular on the island, with the latter offering twinkling blue waters and white sands.
