A magnificent spot, offering breathtaking views. The two trails leading to the gorge are also very beautiful. Be careful on the descent; despite the improvements, it remains dangerous.

Immediately to the right of the church is a path leading down to the sea. The first section runs along a cow pasture, then it becomes very narrow, only two feet wide, and very steep. You pass under bushes, along slopes and precipices, along paths, and over steps. It's a steep descent, with railings not everywhere. Be careful: not all railings are stable, and in some places you're walking right along the precipice. The last stretch to the pebble beach is made up of rocks covered in algae, and it's slippery in places. The view is magnificent, and the hike a triumph, but not entirely without excitement or danger. The last stretch along the precipice is not suitable for children. When we were there, the wind was strong, force 5, with gusts of up to 6.7.

Magnificent place, be careful however with the accessibility with children. The view is there reward of the km route, and it is only the beginning, because the landscapes are diverse and varied as well as the terrain, but we recommend in dry weather if possible. Route from Sainte-Marguerite-sur-Mer to Varengeville returns GR 21

The natural monuments around Dieppe are primarily defined by the dramatic chalk cliffs of the Alabaster Coast. These towering white cliffs, composed of layers of chalk and flint, reach up to 106 meters high, as seen at the White cliffs near Criel Plage. The landscape is continuously sculpted by erosion, creating impressive landforms and pebble beaches at their base. You'll also find 'valleuses,' which are steep-sided valleys that cut through the cliffs, providing unique access to the sea.
Yes, several natural monuments are suitable for families. Petit Ailly Beach is a family-friendly spot nestled in a small valley, offering magnificent views. The Cap d'Ailly Protected Natural Site also welcomes families, combining cliffs and greenery with opportunities to relax and enjoy nature. Dieppe Beach itself is popular for family strolls and activities, featuring a long promenade and supervised swimming during summer months.
Dieppe and its surroundings are known for their distinctive pebble beaches. Dieppe Beach is a popular 1.5-kilometer stretch ideal for strolls and water sports. Other notable pebble beaches include Petit Ailly Beach, which offers stunning views, and Mesnil-Val Beach. Quiberville-sur-Mer Beach is distinguished by its white cabins and reveals a stretch of sand at low tide. These beaches are often found at the base of the dramatic chalk cliffs.
Absolutely. The natural monuments around Dieppe offer excellent opportunities for hiking and walking. Paths like the GR21 run along the clifftops, providing spectacular panoramic views of the English Channel. The 'valleuses' such as Moutiers Gorge and Valleuse de Vasterival offer unique, sometimes steep, trails down to secluded beaches. The Cliffs of Sotteville-sur-Mer Coastal Path is another great option for a scenic walk.
The entire Alabaster Coast offers breathtaking views from its clifftops. Specific highlights include the Viewpoint overlooking the cliffs of Le Tréport, which provides a stunning panorama. The Cap d'Ailly Protected Natural Site also offers impressive views of the English Channel and its lighthouse. Many points along the GR21 hiking path provide excellent vantage points to appreciate the scale and beauty of the white cliffs.
While primarily natural, some sites hold historical importance. Dieppe Beach, for instance, was the site of the Dieppe Raid during World War II, making it a place for both relaxation and reflection. The dramatic scenery of the Alabaster Coast has also inspired many Impressionist painters, including Monet, Renoir, and Pissarro, who depicted the ever-changing light and textures of the environment.
The Cap d'Ailly Protected Natural Site is particularly rich in biodiversity and serves as an important ornithological location. Here, you might spot various bird species such as the boreal and black tit, long-eared owl, little owl, and northern fulmar. The combination of cliffs and greenery provides diverse habitats for local fauna.
The natural monuments around Dieppe can be enjoyed year-round, but the summer months (July and August) are popular for beach activities, with supervised swimming available. Spring and autumn offer pleasant temperatures for hiking and exploring the clifftops and valleuses, often with fewer crowds. Visiting at the end of the day, especially at places like Les Petites Dalles, can reveal a reddish hue on the cliffs as the setting sun brings out the iron in the limestone.

You can find routes for gravel biking, such as the 'White cliffs – Port Entrance View - Dieppe loop,' or explore cycling paths like the 'Seaside Cycle Route: Cliffs of Criel Loop.' For mountain biking enthusiasts, trails like the 'Sainte-Marguerite Church – Ailly Lighthouse loop' are available.

Valleuses are unique geological formations along the Alabaster Coast: small, steep-sided valleys or gorges that cut through the cliffs, providing access to the sea. Notable examples near Dieppe include Moutiers Gorge in Varengeville-sur-Mer, which leads to a beautiful beach with views of the Saint-Valéry church. Another spectacular example is Valleuse de Vasterival, known for its narrow corridor between chalk walls leading to the water.
While beautiful, the cliffs are subject to collapses due to continuous erosion. It is important to exercise caution and avoid walking too close to their base, especially during high tide or after heavy rain. Always stay on marked paths when on the clifftops and be mindful of warning signs. Some descents to beaches, like parts of Moutiers Gorge, can be steep and slippery, requiring careful footing.
For those seeking tranquility, Varengeville-sur-Mer Beach, less than 10 km from Dieppe, is often less crowded and offers exceptional panoramic views of the chalk cliffs. Access is typically via a valley, best explored on foot. The secluded beaches found at the end of valleuses, such as Valleuse de Vasterival, can also offer a wilder, more intimate experience away from the main tourist spots.
