Kos is the Dodecanese island where ancient medicine and an easy beach holiday share the same coastline: the birthplace of Hippocrates, with the terraced Asklepieion sanctuary above the sea, a Knights of St John castle on the harbour, a flat, bike-friendly main town and long sandy beaches down the north coast.
This guide covers the island properly, with 21 things to do including old town walks, the Asklepieion, sunset in the mountain village of Zia, off-road safaris, a hamam, tastings of local wine, oil and honey, and boat days to Pserimos and the nearby islands or across to the volcano on Nisyros. It pairs those with 10 hotels in Kos Town, Lambi, Psalidi, Mastichari and Kefalos, and six planning guides on where to stay, how to eat well, when to go and which day trips to choose.
The hillside healing sanctuary where Hippocrates is said to have taught, with three terraces of temples and baths looking across the water to Turkey. Best seen with a guide who can explain the medicine.
A guided stroll through the compact centre of Kos Town, taking in the harbour, the castle walls, the Ancient Agora and the plane tree linked to Hippocrates.
A low-cost, self-paced puzzle walk through Kos Town that turns the main sights into clues and challenges, handy for families and independent travellers.
A full-day excursion to the volcanic island of Nisyros, with a walk around the crater floor, the whitewashed village of Mandraki and a long lunch by the sea.
A highly regarded full-day boat cruise to three islands with four swimming stops in clear water, a relaxed pace and plenty of time for sun and snorkelling.
A well-reviewed three-island cruise that adds an audio guide to the swimming and sunbathing, handy for travellers who like to know what they are looking at.
A four-class waterfront hotel in the middle of Kos Town, a few minutes on foot from the Tree of Hippocrates, the Ancient Agora, the port and the castle, with a pool and a sea-view restaurant.
An adults-only boutique hotel and spa right on Lambi Beach, rated very highly, with suites, a private beachfront and Mediterranean dining. It closes for the winter.
A very large all-inclusive resort on the north-west coast with 329 rooms, direct beach access, indoor and outdoor pools, a spa, a kids club and a winery. It is closed from late autumn to spring.
A small, simple two-class hotel in Kefalos with a seasonal pool, free continental breakfast and Kefalos Beach three minutes on foot. A quiet base for the far south-west.
