The landscape of the centre of the island is volcanic and flat by comparison with either of its extremities— a raised plateau of pumice, riven by the gullies of sea sonal torrents, forming a long neck or isthmus linking the mountains of the Kephalos peninsula in the west to the Horomedon massif in the east. This is, in effect, the sunken rim of the ‘Kos Caldera’, which erupted 160,000 years ago, and stretches under water to the active volcano of Nisyros to the south. It has created a landscape of long bays, splendid beaches, and wide views.
