Kos

Long, green and unusually flat, Kos is the second-largest of the Dodecanese and one of the easiest Greek islands to explore. As the birthplace of Hippocrates, the father of medicine, it wears its ancient heritage lightly, scattering Hellenistic ruins, Roman mosaics and a medieval castle among modern beach resorts and bicycle lanes. The result is an island that appeals equally to history lovers, families and cyclists.

Kos Town, the capital and main port, is the natural starting point. Here the imposing Castle of the Knights of Saint John guards the harbour, while the ancient Agora, Roman Odeon and the famous Plane Tree of Hippocrates sit within easy walking distance. Just outside town lies the island's greatest treasure, the Asklepion, a terraced ancient healing sanctuary with panoramic views across the strait to Turkey.

Beyond the capital, Kos unfolds into a string of beaches and villages. The southern coast around Kardamena, Paradise Beach and Agios Stefanos offers long stretches of golden sand and shallow, family-friendly water. In the island's mountainous spine, the village of Zia is celebrated for its sunset views over the Aegean, its craft shops and its hearty tavernas. Cyclists appreciate the flat coastal terrain and dedicated bike paths that make getting around a pleasure rather than a chore.

The best months are May, June and September, when the sea is warm, the light is soft and the resorts are lively without being overwhelmed. July and August are hot and busy, filled with charter flights and package holidaymakers, but the island is large enough to find quieter corners. Spring brings green hills and wildflowers, while winter is mild but sleepy, with most tourist businesses closed.

What sets Kos apart is its blend of accessibility and depth. Its international airport receives direct flights from across Europe all summer, and frequent ferries link it to Rhodes, Bodrum in Turkey and the smaller Dodecanese islands. Whether you come for the archaeology, the beaches or simply to pedal between them, Kos offers a relaxed, rewarding and remarkably varied island holiday.
