From here you can appreciate the cliffs south of Tréport. Be careful if you have vertigo, because the cliffs are really impressive! Chalk walls where a particular vegetation has adapted to the difficult conditions of the ground. If you ever need to orient yourself, a sign of arrows shows you the distance to major cities: Paris, London, Beauvais, etc.

White cliffs

Highlight • Natural Monument

The highest cliffs in Europe (106 m on the Mont-Joli Bois) majestically frame Criel pebble beaches.

The cliffs of Criel-sur-Mer are among the highest in France, with 106 meters above sea level. This town extends along the Yères valley. A nugget to admire as soon as possible: coastal erosion and the retreat of the cliffs jeopardize the future of the seaside resort in the decades to come. Take the opportunity to go to the beach and contemplate this open-air fresco.

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.

A small, peaceful beach, ideal for relaxing and admiring the beautiful scenery. The GR 21 hiking trail passes just a few meters above.
