Santorini is high on everybody’s cruising checklist, a sheer, towering semicircle of extinct volcano, the black cliffs topped with white sugar-cube houses, the light more dazzling than anywhere in the Mediterranean.

Ships moor up to giant concrete pontoons at the foot of the cliff (the sea is too deep to anchor here) and passengers pour ashore to ascend the zigzag cliff path to Thira, the chichi capital, or to take a bus to Oia, a gorgeous arty village at the tip of the caldera. It’s from here that you’ll get that classic Mediterranean photo of the blue-domed Cycladean churches with your ship basking in the glittering, sapphire-blue sea below.
