Discover the Railway Heritage and the Network of Sea Baths in the Bay of Somme
The Baie de Somme Railway offers you the opportunity to travel by historic trains, on the former "Réseau des Bains de Mer".
This network of local interest, opened in 1887, has been entirely preserved by our Association since 1971.
Travelling on board our trains is like diving into a "Belle-Epoque" atmosphere, at the rate of 25 km/hour to discover a collection of railway equipment restored over the years by a team of enthusiasts.
The Network of Sea Baths cross landscapes that differ according to the seasons.
You can reach the seaside resorts of Cayeux-sur-Mer, Saint-Valery-sur-Somme and Le Crotoy.
The Gare de Noyelles-sur-Mer provides the connection, as at the time of the Economic Railways, with the SNCF line "Paris-Boulogne-Calais".
