Located just west of Bordeaux, between the Landes pine forest and the Atlantic ocean, the mighty dune du Pilat is a great place to view both land and sea! It is almost 3km long, just a little over 106 meters high and more than 600 meters wide. Each year the measurement has to be recalculated, as the dune is still in movement and it continues to advance inland, through the forest from one to five meters per year.
