The cliffs are made of chalk and are impressive to look at.

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 Petit Blanc-Nez is a cliff in the Pas-de-Calais region and is part of the Deux-Caps (Two Capes) area, which also includes Cap Gris-Nez. Both are part of the protected area classified as a Grand Site de France and offer breathtaking views of the English Channel and, on a clear day, the English coast.

Ault is a beautiful place. Beautifully laid out paths above and below the impressive cliffs. The town center is perfect for relaxing. There are a few cafes and bistros for when you get a little hungry. There are benches everywhere where you can sit and enjoy a few minutes of peace and the wonderful views.

In Hauts-de-France, "canyons" primarily refer to deep valleys, ravines, and distinctive geological features, often carved into chalk and limestone formations. These include dramatic coastal cliffs and serene inland wooded areas, offering varied terrain for exploration rather than the deep, narrow gorges found in mountainous regions.
The region boasts several unique geological features. The Ault Chalk Cliffs present a dramatic coastline where chalk meets the sea, sculpted by erosion. Inland, the Pihem Ravine offers a peaceful spot with wooded slopes and winding paths, showcasing the region's forested terrain.
Yes, the Opal Coast features impressive formations. The Cran d'Escalles is a distinctive valley carved into white chalk cliffs, offering panoramic views of the English Channel and a natural arch. Similarly, the Ault Chalk Cliffs provide a rugged and visually captivating coastline.
Beyond the coast, inland valleys like the Vallée de Noé offer typical French countryside views with a mix of woods and fields, perfect for quiet strolls. The Pihem Ravine is another peaceful spot with wooded slopes and winding paths, providing a glimpse into the region's more undulating and forested terrain.
The areas around these geological sites are excellent for hiking. For example, near the coastal cliffs, you can find routes like the "Balconies of Escalles Trail." For more general hiking, explore the various options in the region by checking out the Hiking around Hauts-De-France guide, which includes routes in the Parc naturel régional des Caps et marais d'Opale.
Yes, many areas are suitable for families. The Vallée de Noé is noted as family-friendly, offering beautiful views between woods and fields. For easy hikes, the Easy hikes around Hauts-De-France guide lists several routes, such as "Dunes de la Slack" and "Sentier du Fartz," which are generally accessible for all ages.
The best time to visit for outdoor activities and enjoying the natural sites is typically during spring (April to June) and early autumn (September to October). During these periods, the weather is generally mild and pleasant for hiking and exploration, and the landscapes are particularly vibrant.
Visitors frequently appreciate the stunning coastal views, especially from sites like Cran d'Escalles, which offers breathtaking panoramas of the English Channel. The peaceful, natural settings of inland ravines and valleys, such as the Pihem Ravine, are also highly valued for their serene atmosphere and opportunities for quiet walks amidst nature.
While not open-air canyons, the geology of Hauts-de-France, particularly its chalk formations, is prone to karst phenomena. This includes sinkholes (dolines) and underground cavities, especially in the Paris Basin which covers part of the region. These are fascinating geological features, though they don't typically manifest as visible gorges.
Yes, the Verdonnelle Valley is described as a superb, wild, and hilly place, appealing to those seeking a more rugged outdoor experience. Be aware that road conditions might be poor in places, making some activities like cycling potentially challenging.
Yes, the Cave of the Three Children is noted as a significant natural formation. While details on its specific gorge-like qualities are limited, its inclusion suggests it's a notable site involving carved rock or underground features worth exploring for those interested in geological formations.
