“The 100 Loveliest Detours in France” is an association of little towns in France which are not on the main roads but which possess top-level tourist, heritage and cultural interest. The town of Châteaudun has been part of the network since it was set up in 1998.
The Guide to the Best Detours in France 2025 is available for free at the Tourist Information Office reception desk in Châteaudun (this guide cannot be sent by post).
