Étretat is best known for its cliffs, including a famous natural arch. These cliffs and the associated resort beach attracted artists including Eugène Boudin, Gustave Courbet and Claude Monet.
Two of the three famous arches seen from the town are the Porte d'Aval, and the Porte d'Amont. The Manneporte is the third which can not be seen from the town.

Etretat is found in the Seine-Maritime department of Normandy, 20 kilometres north of Le Havre.
Etretat is on the Normandy coast, and is best known for its picture postcard white cliffs, and the arches and tunnels in the cliffs that jut out to sea, and a large rock needle. Monet, Maupassant and Flaubert were all enthusiasts of the region around the town.
When you have had enough of striding around on the clifftops admiring the views, and have ambled along to the little Notre Dame church, the town itself deserves a visit.
Etretat itself is quite an attractive little town - from the beach in the town you can further admire the cliffs to either side, then you should take a look in the old market hall, that has been attractively restored, although it is more devoted to tourist shops than fruit and vegetables now, unfortunately.
