💡 Tips
- As Petit-Caux covers 18 different villages, having a car is highly recommended to explore its spread-out attractions.
- Check tide schedules before going down to the pebbly beaches, as the sea comes right up to the cliffs at high tide.
- Look for the distinct valleys ('valleuses') that provide rare access paths down to the sea through the high cliffs.
- Prepare for spotty mobile reception in some of the deeper coastal valleys.

Petit-Caux is a prominent French 'commune nouvelle' established on January 1, 2016, in the Seine-Maritime department of Normandy. It was formed by the merger of 18 distinct villages, creating a large administrative area that stretches across the photogenic Alabaster Coast. The town is globally significant in the energy sector as it hosts the Penly nuclear power station, which is a major contributor to France's national power grid. Geographically, the area is defined by the high chalk cliffs and small valleys, known as 'valleuses', that provide the only access points to the pebble beaches below. The cultural heritage of Petit-Caux is diverse, encompassing everything from Romanesque and Gothic churches to sites associated with the 1942 Dieppe Raid during World War II. Its economy is a mix of high-tech energy production, traditional agriculture, and growing coastal tourism. Visitors are drawn to its extensive network of hiking trails, modern sports facilities like the Ludibio complex, and the unique charm of its numerous small hamlets, each offering a window into the timeless character of the Pays de Caux region.
