The Petrified Forest of Lesvos: A Complete Visitor Guide
The Petrified Forest of Lesvos is one of the largest petrified forests on Earth, created around 20 million years ago when volcanic ash buried an entire subtropical woodland. It spans four separate park sites near the village of Sigri in western Lesvos. No public transport reaches the parks. A car or private tour is the only practical way to see it properly. Entry to the museum costs €10 and includes access to the forest park sites on land.
What Is the Petrified Forest of Lesvos?
The Petrified Forest of Lesvos is a UNESCO Global Geopark where ancient trees were buried under volcanic ash around 20 million years ago. Over millions of years, minerals slowly replaced the organic material, turning entire trunks, root systems, and branches to stone. Today, you can walk among them.
Scientists have called it "the Pompeii of the plant world." That's not marketing. At the main Forest Park, you can stand next to a standing petrified tree with a circumference of 13.7 metres, the thickest on Earth. Another trunk stands 7.02 metres tall, the tallest petrified tree in Europe.
The forest covers around 150 square kilometres of western Lesvos, spread across the area between the villages of Sigri, Antissa, and Eressos. It's not a single tidy site with a car park and a gift shop. It's a geological phenomenon scattered across a landscape, and that's exactly what makes it so extraordinary.
It also means most visitors only scratch the surface.
What Will You Actually See?
There are four fossil-bearing parks open to visitors, managed by the Natural History Museum of the Lesvos Petrified Forest:
- Sigri Park, right next to the Natural History Museum in the village
- Nisopi Park, on a small islet just offshore from Sigri
- Plaka Park, a few kilometres north of Sigri
- The Forest Park, the main site, located several kilometres outside the village
Each site looks different. The trunks come in deep reds, yellows, greens, and blacks, coloured by the minerals that replaced the original wood over millennia. Some stand upright, still rooted in place. Others have fallen but remain intact, with root systems exposed and perfectly preserved.
The Forest Park is the highlight. Walking among trees that were alive when Europe looked nothing like it does today is a quiet, strange, genuinely moving experience. The landscape is open and rocky, with sea views in the distance. It doesn't feel like a museum. It feels like deep time.
On the island of Lesbos, few places leave an impression quite like this one.
The Natural History Museum at Sigri
Start here before visiting any of the parks. The museum gives you the scientific context that turns a walk among old rocks into something you'll actually understand and remember.
The Natural History Museum of the Lesvos Petrified Forest opened in 1994 and sits at the edge of Sigri village. Inside, you'll find fossil specimens, geological timelines, and exhibits explaining how the forest was created and what this part of the Aegean looked like 20 million years ago. It's well-designed and genuinely interesting, even if natural history museums aren't usually your thing.
Your entry ticket costs €10 and covers the museum plus the land-based forest parks: Sigri Park, Plaka Park, and the main Forest Park. It does not include the Nisopi Marine Petrified Forest Park, which is only accessible by the glass-bottomed boat. That's still excellent value for what you get.
One extra worth booking: a glass-bottomed boat departs from Sigri port every day at 10:30 and takes you around the Nisopi islet, where you can see petrified trunks below the water. The boat ticket costs €15, sold separately. Contact the museum in advance to reserve your spot: info@lesvosmuseum.gr or +30 22530-54434.
If you're travelling in a group of six or more, you can also arrange to be accompanied by a geologist. Very few ancient sites anywhere offer that kind of access.
How to Get to the Petrified Forest
You need a car or a private transfer. There is no public bus to any of the park sites.
Sigri sits in the far west of the island. From Molyvos in the north, it's around 80 kilometres along winding mountain roads through some of the most beautiful and empty countryside on Lesvos. Allow roughly 1.5 hours each way. From Mytilene in the south, the drive is similar, around 90 kilometres.
The museum's own visitor information confirms that a car is necessary to reach the main Forest Park from Sigri. And that's just one of four sites. The parks are spread out. Getting between them without your own transport means missing most of what's there.
This is the honest reality: to visit the Petrified Forest of Lesvos properly, you need transport and time. Getting lost on unmarked tracks between sites in the midday heat is not the experience you're after.
A private tour from your accommodation takes care of everything. You leave when you want, stop where you want, and travel with a driver who knows these roads. Explore our private tours.

When Is the Best Time to Visit?
The best months to visit the Petrified Forest are May–June and September–October. The weather is warm but manageable, crowds are smaller, and the quality of light is better for photography.
July and August are hot across Lesvos, and western Lesvos is also one of the windier parts of the island. The park sites are exposed with very little shade. It's not impossible in peak summer, but if you go then, start early and bring more water than you think you need.
Spring is the best season, in our opinion. The hills around Sigri turn green after the rains, wildflowers grow up around the ancient trunks, and you can often have the Forest Park almost to yourself.
Tips Before You Go
Wear proper shoes. The park surfaces are uneven rock and gravel, and sandals that work fine for Sigri village won't cut it on the forest trails. Bring more water than you think you need, and don't skip the sun protection. Most of the sites offer very little shade, and that catches a lot of visitors off guard.
Give yourself enough time. If you want to visit the museum and two or three of the parks, plan for a full day rather than half. The drive from most parts of Lesvos is long enough that rushing makes no sense, and the sites deserve more than a quick pass.
Think about combining the Petrified Forest with nearby stops. Sigri village is a lovely spot for lunch, and Skala Eressos, just 14 kilometres to the south, has one of the best beaches on Lesvos. A private tour can easily fold both into the day. See our Western Lesvos day tour.
Finally, book the glass-bottomed Nisopi boat before you arrive. It fills up quickly in summer, and it's the kind of thing you'll regret missing. Contact the museum directly to reserve your spot: info@lesvosmuseum.gr or +30 22530-54434.
Book a Private Tour to the Petrified Forest
GoLocal offers private tours to the Petrified Forest. We know the roads, we know the timing, and we know which sites to prioritise depending on how much time you have.
You get door-to-door pickup, a comfortable vehicle, and a day that runs on your schedule. We can build in the museum, the Forest Park, lunch in Sigri, and a swim at Skala Eressos on the way home. Or keep it simple and focused. Your call.
This is one of the most remarkable natural sites in all of Greece, and it sits right here on Lesbos. It deserves more than a rushed half-visit.
Come and see it properly.
