From this vantage point, you have a fantastic view of the dune. Unfortunately, there was a fire, and hardly any forest remains.

It's worth walking just a few hundred meters further. There you have the dunes almost to yourself.

The Pilat dune is the highest in Europe. Despite its size, it is fragile. The climb is worth it! The bravest don't take the stairs: the sand will heat up your thighs and calves! The view at its top is breathtaking.

The Pilat dune is the highest dune in Europe, with more than 100 meters measured in 2020. It extends more than 600 meters from east to west and 2.9 kilometers from north to south. Located at the entrance to the Arcachon basin, the Pilat dune is a tourist spot, and therefore sometimes very busy. But by arriving via the cycle path, you avoid traffic jams and can admire the dune quietly. Plan to attach the bikes at the bottom if you want to enjoy the impressive panorama seen from above.

For thousands of years nature has been piling up the Dune du Pilat. Most of the sand masses are carried away by the wind from the offshore Banc d'Arguin sandbank or washed up by the Atlantic. And the process today. The dune, which is under nature protection, is a shifting dune: it steadily makes its way inland and gradually buries the adjacent forest to the east like a steamroller. And with up to five meters per year, it's actually quite fast! On the east side, the Dune du Pilat can be climbed. A staircase is specially installed for this between approximately April and November. The more adventurous dare to climb directly on the sand, so you have to be in good physical condition. Climbing the dune is worth it either way. From the top you have a wonderful view of the blue, endless Atlantic, the Cap Ferret peninsula and the Bay of Arcachon on one side and the gigantic pine forest on the other. However, the highest point of the dune is not directly at the top of the stairs, but about a kilometer further south. For this reason alone it is worth planning a longer trip to the Dune du Pilat. A hike on the mountains of sand, which always give way slightly under your feet, is something very special. In the south you can still marvel at the hustle and bustle of paragliders, jet skis and sailing boats while enjoying the view and gradually making your way back north across the sandy beach. Here you can see that the dune looks no less spectacular from below. And best of all: a visit to the dune is completely free and possible all year round! https://www.camperdays.de/blog/europa/dune-du-pilat.html
