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.

The cliffs are simply a dream. A highlight of a holiday in Normandy. I highly recommend a hike right along the cliffs. There's something for everyone, whether it's a short or long hike.
