Sigri petrified forest

For weirdness alone, this sci-fi-like spot demands a closer look. An ancent pine and redwood forest, it was fossilised 20 million years ago when an erupting volcano covered the trees in hot ash, turning them to solid stone.

Take a tour around the park, which is speckled with the bizarre petrified stumps that once flourished here.

Today, two thirds of Lesvos is covered by volcanic rock.
