Réserve naturelle nationale des coteaux de la Seine, National nature reserve in Bennecourt, France.
The Réserve naturelle nationale des coteaux de la Seine covers limestone slopes along a bend of the Seine River across five municipalities. The area features white chalk cliffs rising above valleys and creates a diverse landscape of hillsides and river plains.
The area was shaped by farming until World War II, with small fields, orchards, and vineyards covering the slopes. After the war, these lands were left behind and returned to wild growth.
The white chalk cliffs have attracted painters since the 19th century, who captured the dramatic rock formations in their work. Today, the landscape continues to shape how people see this part of the Seine valley and its rare plant life.
The reserve is best explored on foot, with hiking trails that wind through the slopes and offer views of the river and valleys. The paths vary in difficulty, so wear sturdy shoes and allow time to walk at a relaxed pace.
The reserve is home to roughly 470 plant species, many found nowhere else in this region and adapted to the limestone rocks. Bird watching is rewarding here, as the river bend serves as a stopping point and nesting ground for migrating species.
