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
