Why Visit Kos
Kos is the third-largest island in the Dodecanese and the birthplace of Hippocrates, the father of Western medicine. The Asklepion, a terraced healing sanctuary built into a hillside 4 km from Kos Town, is where students of Hippocrates practised medicine in the 4th century BC — the ruins include temples to Asclepius and Apollo spread across three levels with sweeping sea views. In Kos Town, the gnarled Hippocrates Tree anchors Platanos Square, where legend says Hippocrates taught his students beneath a plane tree. The town itself is compact and bike-friendly, with the Neratzia Castle (built by the Knights of St John), a Roman Odeon, and the Casa Romana mosaic villa all within walking distance. The island 112 km coastline delivers a wide range of beaches: Tigaki for families, Agios Stefanos for ancient ruins alongside golden sand, Paradise Beach for the unique Bubble Beach phenomenon where volcanic gas rises through the seabed, and Therma for a hot-spring soak where geothermal water meets the sea. Inland, the mountain village of Zia draws sunset-seekers, while the abandoned Byzantine settlement of Palio Pili rewards hikers with castle ruins and panoramic views.
