Here in Ault begin the chalk cliffs, which stretch all the way to Normandy and repeatedly appear as enormous cliffs.

The cliffs around the beach of Ault are composed of chalk from the Upper Cretaceous, more precisely from the Turonian and Coniacian (around 83 million years ago to 90 million years ago). They are strewn with flint nodules which highlight the subhorizontal stratification planes (the formation of flint has already been discussed in Discovery of the geology of the cliffs of Étretat, presentation of an excursion from the beach of Tilleul (Antifer) to the Porte d'Amont (Étretat Nord)). The relative proportion of chalk and flint is around 90-95% chalk to 5-10% flint. Flint horizons are stratigraphic markers. On the cliffs of Ault, the regular flint band called Seven Sisters is recognizable and characterizes the boundary between the Middle Coniacian and the Upper Coniacian (around 87 million years ago). The boundary between the lower and middle Coniacian is marked by the Shoreham 2 marl level, which is more difficult to identify. These lithostratigraphic markings allow in particular the correlation of distant deposits, such as between the Normandy and Picardy coasts, or between the French and English coasts.

The Ault Chalk Cliffs offer impressive formations along the Normandy Alabaster Coast, while the Cliffs of Ault mark the beginning of the Normandy cliffs, providing vast views towards the Bay of Somme and Le Havre.
Yes, the Viewpoint overlooking the cliffs of Le Tréport allows you to appreciate the impressive chalk cliffs south of Tréport. Additionally, the White cliffs near Criel Plage are among the highest in Europe, reaching up to 106 meters on Mont-Joli Bois, offering spectacular vistas.
The natural monuments around Eu are primarily composed of chalk from the Upper Cretaceous period, dating back approximately 83 to 90 million years. These chalk formations often contain flint nodules, which highlight the subhorizontal stratification planes. The cliffs are a testament to millions of years of geological activity and erosion.
The region offers a variety of outdoor activities. You can find numerous routes for hiking, including moderate trails like the 'Eu and Le Tréport Loop'. For cyclists, there are road cycling routes, and runners can explore various running trails, often with coastal views.
Absolutely. Many of the natural monuments are accessible via hiking trails. For example, you can follow paths along the edge of the La Cise Cliff, starting from Ault, to enjoy panoramic coastal views. The coastal trail along the cliffs near Le Tréport also offers excellent hiking opportunities.
Visitors frequently appreciate the dramatic coastal views, the unique geological formations of the chalk cliffs, and the opportunities for scenic walks. The area's natural beauty, especially the interplay of white cliffs and the English Channel, is often highlighted in visitor feedback and photos.
While specific family-friendly amenities are not detailed, the general nature of coastal walks and viewpoints can be enjoyed by families. However, some cliff-edge paths may be steep or subject to erosion, so caution is advised, especially with young children. Always check local signage and conditions.
Yes, several natural monuments are located near or directly overlook beaches. For instance, the La Cise Cliff overlooks the Bay of Somme, and the White cliffs majestically frame Criel's pebble beaches. The village of Ault also features a sandy beach at low tide.
For photography, early morning or late afternoon often provides the best light. The White cliffs of Criel Plage, for example, are said to offer a magnificent spectacle at sunset, when they can take on beautiful pink highlights.
When exploring the cliffs, it's important to be aware that some passages can be very steep, and the limestone rock is subject to erosion. Always stay on marked paths, keep a safe distance from cliff edges, and be mindful of changing weather conditions. If you experience vertigo, be particularly cautious at high viewpoints.
