Réserve naturelle nationale des coteaux de la Seine, National nature reserve in Bennecourt, France.
The reserve spans 268 hectares across limestone slopes in five municipalities, featuring chalk cliffs overlooking the Seine River meander and Epte Valley.
The site transformed from small crops, orchards, vineyards, and pastures to its current natural state following agricultural abandonment after World War II.
The limestone cliffs and chalk pinnacles drew numerous painters who captured the natural formations, marking the first chalk cliffs before Normandy.
The reserve contains marked hiking trails, including a 2-kilometer interpretive path along the GR 2 between Chantemesle and Haute-Isle.
The protected area contains 470 plant species, with 59 classified as rare in Ile-de-France, including regional specialties like the Montpellier milk-vetch.
