OVERVIEW

The mind boggles at the age of the Petrified Forest of Lesvos. Frozen in time after volcanic ash rained down on this part of the North Aegean up to 20 million years ago are the remnants of the trunks, branches, roots, leaves, seeds and even some animals that once flourished within an ancient forest and have now been fossilized in what today constitutes a veritable monument of nature. It’s been called "the Pompeii of the plant world" and is part of UNESCO’s World Geoparks Network

Central to understanding this astonishing legacy is to visit the forest’s excellent Natural History Museum, just outside the town of Sigri. The museum is literally built around a number of fossilised tree trunks, lying exactly where they fell millions of years ago.
 
From here you can explore further afield, with a newfound appreciation for these relics of nature, whose colours (red, yellow, green and chestnut) are so striking against the volcanic ash-coloured rocks around them.

DON'T MISS

Natural History Museum of the Petrified Forest 

With exhibition rooms dedicated to the “Fossilised Forest” and the “Aegean Evolution”, the museum will open your eyes to the evolution of the unique ecosystem of the ancient forest and other artefacts from the Palaeolithic Age. By far the best experience is to be shown around by one of the museum’s geologists.  

Sigri Park

You emerge from the museum onto a path leading to a collection of fossilised trees. 

Plaka Park 

Around 800m south of Sigri is another park, covering several hectares. Look out for the largest petrified tree trunk, with a circumference of 13.7m! 
 

Nisiopi island

The museum has a glass-bottomed boat that visits nearby Nisiopi (or Megalonisi), where hundreds of petrified logs (some wholly or partially submerged) have created an entire island geotope. Waves on the western side of the island have revealed giant conifers that are ancestors of today’s sequoias.

Walking paths

A number of hiking trails are marked out around the Petrified Forest, including a path to the village of Eressos (6km) and one that follows the Tsichliontas Valley and leads to the Hamandroula Park, before joining the road between Sigri and Eressos (13km).
