Etretat is best known for its chalk cliffs, including three natural arches and a pointed formation called L'Aiguille or the Needle, which rises 70 metres (230 ft) above the sea. Some of the cliffs tower 90 metres (300 ft) over the Atlantic Ocean. These natural wonders are freely accessible, as is the white pebble beach. Claude Monet and other Impressionists famously painted the arches and cliffs in the nineteenth century. An Arsène Lupin story was based here while Guy du Maupassant spent most of this childhood in the town.
