Réserve naturelle nationale de l'estuaire de la Seine

The Réserve naturelle nationale de l'estuaire de la Seine stretches across a large coastal zone with tidal flats, wetlands, and reed beds. This protected area contains diverse habitats where numerous plant and animal species live in their natural state.

This area once served industrial purposes until the late 1990s when it became a protected reserve. The shift from industrial use to natural protection marked a major turning point in how the region was managed.

This estuary is a working landscape where nature's cycles shape everything visitors see and experience. The tidal rhythms, seasonal bird arrivals, and plant growth patterns are woven into how the place functions and what makes it special to people who visit regularly.

The reserve provides accessible trails and viewing platforms for exploring the habitats and observing wildlife. Visitors should wear weather-resistant clothing and check tidal times, as water levels significantly affect which areas are easiest to reach.

The reserve hosts hundreds of bird and plant species, with many found nowhere else in the region. This biological diversity makes it an important place for understanding how coastal ecosystems function and what species depend on estuary habitats.
