The Verdict

A bare limestone island of sponge divers and rock climbers: steep cliffs, deep water, and a season that runs outside summer.

Why go

Kalymnos is limestone from top to bottom and steep everywhere, which makes it one of the best climbing destinations in Europe and an awkward place to farm. The diving past is still alive in the harbour at Pothia — sponges are sold on the quay and the boats that went out for them are remembered in a small museum. The coast road runs the length of the island with coves below it, and the village of Vathi sits at the head of an inlet that looks like a fjord. Come in spring or autumn for the climbing; the island is at its best when it is not August.
