The Dune du Pilat, on the edge of the Arcachon Bay in France's Nouvelle-Aquitaine region, is the tallest sand dune in Europe. It stretches roughly 2.9 km north to south and about 600 m east to west, with a summit that shifts around 100 m in height (it peaked near 110 m in 2017, then fell through storms and erosion to about 101 m as measured in 2025). Westerly winds keep carrying sand from the offshore Arguin sandbank, pushing the dune eastward 1–5 m a year as it slowly buries the pine forest behind it — a genuinely 'living' dune that draws about two million visitors annually, making it one of France's most popular natural sites. The main draw is the summit panorama over the Atlantic, the Arguin sandbank and the vast Landes forest.
Summit panorama: a 360° view with the Atlantic, the Arguin sandbank and Cap Ferret on one side and the endless Landes pine forest on the other
Sunset spot: watching the sun drop into the ocean from the crest is the classic experience — aim for late afternoon
A moving dune: look for tree stumps and forest edges being swallowed by sand, the visible mark of a dune advancing east
Paragliding: gliders launch from the ridge (run by a dedicated school), and tandem flights are available
Banc d'Arguin nature reserve: the protected sandbank at the dune's foot, reached by beach or boat tour, near the oyster-hut villages
Good to know
SafetyThe ocean side has dangerous baïnes (rip currents) and strong currents. Swim only in supervised zones in summer, and on any sandbank always check the tide so the rising water doesn't strand you.
SafetyIn summer the sand gets extremely hot (burns bare feet) and there is almost no shade at the top. Bring water, a hat, sunscreen and shoes; the steep 100 m climb and descent is more tiring than it looks.
SeasonThe 160-step staircase that eases the climb is only installed from Easter to All Saints' (roughly April–November). Off-season you climb directly on the sand, which is far harder — take extra care with slippery footwear, strollers or limited mobility.
SeasonPeak summer brings heavy crowds, parking congestion and higher parking fees. In dry summers the Landes forest carries a high wildfire risk (major fires in 2022), so smoking, open fire and barbecues are banned.
RulesAccess to the dune is free, but parking is paid, and parking is prohibited from 2–5 a.m. with a 50 € penalty. Stay on marked paths and do not trample or damage the marram grass (oyat) that stabilizes the dune.
CautionBeware informal 'parking' touts near the lot and fake booking sites in high season — use only the official parking and official website. Car break-ins and pickpocketing occur in the crowded lot, so leave nothing valuable in your vehicle.
Practical info
The dune is open year-round with free entry; you can reach it from Arcachon station on the Baïa bus (line 1) or by bike on the Vélodyssée, while the car park is paid (car roughly €1–4 in low season, from about €7 for 4 hours in high season; campervans and buses cost more; an annual pass is around €15). Prices, the staircase installation period and bus times change by season, so always confirm the latest details on the official site (ladunedupilat.com) before you go.
