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

However, some paths, like the descent to Moutiers Gorge, can be steep and narrow, making them less suitable for very young children.
The best time to visit is generally during dry weather, especially for coastal paths that can become muddy and slippery. Visiting during low tide is crucial for accessing certain areas like the beach at Moutiers Gorge. Spring and summer offer pleasant temperatures for hiking and enjoying the coastal views, though the Alabaster Coast's beauty can be appreciated year-round, with changing light and colors.
The Cap d'Ailly Protected Natural Site is an important ornithological site, home to a rich biodiversity. You might spot various bird species such as the boreal and black tit, long-eared owl, or little owl. The diverse environments, combining cliffs and greenery, support a range of fauna.

While primarily natural, the Le Bois des Moutiers Park and Gardens, though currently closed for renovation, is a natural monument with significant historical context. It features a house and gardens created from 1898, inspired by the 'Arts & Crafts' movement, with the park entirely planted by G. Mallet in a valley facing the sea. It blends natural beauty with architectural and garden history.
When exploring the Alabaster Coast, be mindful of tidal conditions, especially for beach access. Wear appropriate footwear for potentially muddy or slippery coastal paths and steep descents.
