The Chemin de Fer de la Baie de Somme Routes Explained

The railway offers three main routes, each showcasing a different side of the bay.

Understanding these routes is key to planning the perfect visit.

1. Le Crotoy ↔ Saint-Valery-sur-Somme (The Most Scenic Route)

This is the iconic Chemin de Fer de la Baie de Somme experience.

Running between Le Crotoy and Saint-Valery-sur-Somme, this route crosses stunning salt marshes and coastal landscapes often described as “Between Land & Salt Meadows.”

At low tide, the scenery becomes especially dramatic:

• Reflective surfaces
• Textured sandbanks
• Expansive views across the bay

👉 If you only choose one route, make it this one.

2. Saint-Valery-sur-Somme ↔ Cayeux-sur-Mer (Les Bas-Champs)

This route heads inland toward Cayeux-sur-Mer, crossing wide agricultural plains known as “Les Bas-Champs.”

It’s less dramatic but deeply relaxing:

• Open horizons
• Quiet countryside
• A slower pace

Cayeux-sur-Mer itself is worth visiting for:

• Its long pebble beach
• Colorful beach huts
• Laid-back seaside atmosphere

3. Le Crotoy ↔ Cayeux-sur-Mer (The Full Experience)

Known as the “Great Large,” this is the complete Chemin de Fer de la Baie de Somme journey.

It combines both previous routes, giving you:

• Coastal scenery
• Inland landscapes
• Multiple stops

👉 Best for travelers who want the full experience in one trip.

A Unique Highlight: The Steam Locomotive Switch

One of the most fascinating aspects of the Chemin de Fer de la Baie de Somme is what happens at stations like Saint-Valery-sur-Somme, Noyelles-sur-Mer, and Le Crotoy.

Unlike modern trains, the steam locomotive doesn’t simply reverse direction. Instead, it detaches from the train, moves along a parallel track, and reconnects at the opposite end.

During our journey on the route between Saint-Valery-sur-Somme and Le Crotoy, this became one of the absolute highlights of the experience. At Saint-Valery-sur-Somme, the locomotive is placed on a special turning platform that rotates slightly to guide it onto another track, a rare and fascinating piece of railway engineering that you don’t often see today.

You can step outside and watch the entire process unfold:

• Steam hissing into the air
• Metal clanking as the engine moves
• Slow, precise positioning on the tracks

With the sound, movement, and clouds of steam surrounding the locomotive, it feels like stepping back into another era.

At Noyelles-sur-Mer, the steam locomotive is reattached to the other end of the train after being repositioned.

👉 This is not just a technical maneuver, it’s a key part of the Chemin de Fer de la Baie de Somme experience, and something you definitely shouldn’t miss.

Many visitors say this is one of the most memorable moments of the journey.

What to Expect On Board

The Chemin de Fer de la Baie de Somme is all about atmosphere.

Inside the vintage carriages:

• Wooden interiors
• Large windows (often openable)
• Simple seating

As the train moves, you’ll notice:

• The rhythmic sound of the engine
• Gentle swaying of the carriage
• Fresh coastal air mixed with steam

This is slow travel at its finest.

There’s no rush. No screens. No distractions.

Just the journey.

Our Experience on the Chemin de Fer de la Baie de Somme

We personally took the Chemin de Fer de la Baie de Somme between Saint-Valery-sur-Somme and Le Crotoy, and it quickly became one of the highlights of our trip. The most impressive moment was the locomotive maneuver at Saint-Valery-sur-Somme, where the steam engine is placed on a turning platform that slightly rotates to guide it onto another track. Watching this process up close, with loud mechanical sounds and clouds of steam, is something you truly have to experience yourself.

The ride itself is beautiful, with views over the Baie de Somme, grazing sheep, and plenty of birdlife along the way. We were also lucky to see two steam trains arrive at the same time at Noyelles-sur-Mer, creating an incredible opportunity for photography and video. If you can, plan to spend a full day here so you can also explore Le Crotoy and Saint-Valery-sur-Somme and enjoy some excellent local seafood.
