Chartrettes Bridge

Highlight • Cycleway

Spanning the Seine between Bois le Roi and Chartrettes, this rather calm bridge in terms of traffic, allows you to enjoy a beautiful view of the river and the villas on each bank and the dam in the distance.

Les Affolantes

Highlight • Monument

Located between Seine-Port and Saint-Mammès, these bourgeois villas from the Belle-Époque surprise hikers along the banks of the Seine. Some renowned artists such as Rosa Bonheur or Stéphane Mallarmé come here to seek their inspiration. A neo-Norman style successfully highlighted in the book Les Affolantes des bords de Seine, by Marie-Françoise Laborde.
