The Verdict

Fossilised trees still standing where they grew twenty million years ago, in the dry western corner of Lesvos.

Why go

In the west of Lesvos, around Sigri, volcanic ash buried a forest about twenty million years ago and turned the trunks to stone where they stood. You can walk among fossilised trees still upright, roots and rings legible, across a wide dry landscape of low hills — a geology lesson you can put a hand on. The natural history museum at Sigri explains how it happened, and the coast out here is bare and empty, with a castle on the headland above the village.
