05 Sea kayaking

To the west of Santorini, Milos was formed by a volcanic eruption and its 80-mile coastline is scattered with geological wonders. You have to go by sea, ideally in a kayak, to see its highlights, among them the formations of volcanic ash as white and frothy as meringue, the redand-yellow precipices, and an abandoned sulphur mine with a yellow beach. Also look out for the black basalt cliffs, the towering sea rocks shaped like dancing bears, and the pocket-sized ports with colourful boat garages hollowed out of the stone. Stay at White Rock Milos Suites near the kayak base in Adamas (from £102, B&B).

For jaw-dropping inland views, hire a quad to tackle the road up Profitis Ilias, whose 2,450ft summit makes it the tallest mountain on the island. In the capital, Plaka, you’ll find the nation’s only catacombs and the Archaeological Museum of Milos, which houses a replica of the Louvre’s famed Venus de Milo sculpture. seakayakgreece.com whiterockmilos.com catacombs.gr odysseus.culture.gr
