Discover Baie-de-Somme | A Visitor's Introduction to Baie-de-Somme

Why is Baie de Somme Worth a Visit?

The Baie de Somme is worth visiting for its exceptional natural landscapes, diverse wildlife, and unspoilt coastal charm. Classified as a “Grand Site de France”, the bay is a paradise for birdwatchers, with more than 300 species recorded throughout the year. Its sandy expanses and salt meadows also host France’s largest colony of harbour seals. The landscape is in constant motion, shaped by tides and light, offering a different experience with each visit.

Beyond its ecological appeal, the bay is fringed with storybook towns like Saint-Valery-sur-Somme and Le Crotoy, where visitors can enjoy seafood feasts, scenic walks, and a taste of authentic seaside France. The area also has a strong artistic heritage, having inspired the likes of Victor Hugo and Degas. Whether you're interested in wildlife, photography, coastal cycling, or simply slowing down, the Baie de Somme delivers a wonderfully atmospheric and soul-refreshing escape.

Baie-de-Somme Highlights: Things to See and Do in Baie de Somme

Saint-Valery-sur-Somme

Perched on a hill with sweeping views across the bay, Saint-Valery-sur-Somme is a beautifully preserved medieval town. Its cobbled streets, timber-framed houses, and ancient ramparts tell stories of times past—including Joan of Arc’s brief imprisonment here in 1430. The old town is perfect for exploring on foot, with flower-filled alleys leading to panoramic viewpoints. The port area bustles with cafés, ice-cream stands, and galleries, making it the most popular base for exploring the bay.

Parc du Marquenterre

Located within the northern part of the bay, the Parc du Marquenterre is a world-class bird sanctuary and a must-visit for wildlife enthusiasts. This nature reserve offers over 200 hectares of dunes, marshes, and reed beds, crisscrossed by well-maintained trails and dotted with observation hides. More than 300 species of birds migrate through or nest here, from spoonbills to storks. Guided tours and family-friendly educational activities are available throughout the year.

Seal Watching

The Baie de Somme is home to France’s largest colony of harbour seals and grey seals. You can often see them lazing on sandbanks at low tide, especially near Le Hourdel or from across the bay near Saint-Valery. Guided walks with local experts offer the best chance of spotting them safely and responsibly. These tours are tide-dependent and available throughout the year.

Le Crotoy

Located on the opposite side of the bay from Saint-Valery, Le Crotoy is a charming seaside town with a broad sandy beach and a strong Belle Époque vibe. Unique among towns on the northern coast, Le Crotoy’s beach faces south, making it ideal for sunbathing. The town has a low-key charm with fish markets, little boutiques, and seafood restaurants offering fresh catches straight from the bay.

Chemin de Fer de la Baie de Somme (Bay Steam Railway)

This heritage steam railway offers a delightful journey between the bay’s coastal towns, including Saint-Valery-sur-Somme, Le Crotoy, and Cayeux-sur-Mer. The vintage carriages and scenic route through salt marshes and meadows offer a relaxed and nostalgic way to travel. It’s especially popular with families and steam train enthusiasts.

Cayeux-sur-Mer

Cayeux-sur-Mer is a traditional seaside town with a long boardwalk lined with over 400 colourful beach huts—the longest in Europe. Its pebbled beach is perfect for a bracing walk, and the views of the Channel are wide and wild. The town feels wonderfully untouched by mass tourism and is ideal for travellers seeking peace, sea air, and authenticity.

The Route Blanche

This scenic coastal trail between Cayeux-sur-Mer and Le Hourdel is a favourite among walkers and cyclists. It offers spectacular views over dunes, marshes, and the open sea. The best time to walk the route is early morning or just before sunset, when the light over the bay is at its most magical.

Maison de la Baie de Somme

This excellent nature and heritage centre near Lanchères offers interactive exhibits about the bay’s ecosystems, history, and wildlife. It’s a great place to start your visit, especially with children, and gives valuable context about how the bay’s environment has evolved and been preserved. You can also book guided outings from here.

Horseback Riding on the Bay

For a unique and memorable experience, take a guided horseback ride across the sands at low tide. Several stables in the area, particularly around Saint-Valery and Rue, offer rides for all levels. Galloping across the bay as the sky opens wide above you is nothing short of exhilarating.

Cross-Bay Walks

One of the most iconic activities in the Baie de Somme is the guided crossing of the bay on foot. These walks are only possible with a guide due to shifting sands and tidal conditions, but they offer an extraordinary opportunity to literally walk across one of France’s great natural wonders. It’s an unforgettable experience, offering close-up views of wildlife, seals, and ever-changing light.

Practical Advice for Visitors

Getting There

The Baie de Somme is easily accessible by train, car, or even bike. The nearest major city is Amiens (about 1 hour away by car), and Paris is roughly two hours by road. The closest train stations are Noyelles-sur-Mer (which connects to the heritage steam train), Rue, and Abbeville. Saint-Valery-sur-Somme and Le Crotoy are both reachable via scenic local roads and are good central points for exploring the area.

Driving is the most flexible option for accessing remote nature spots and exploring at your own pace.

Parking

There is ample parking in most of the bay’s towns, including paid car parks in Saint-Valery-sur-Somme, Le Crotoy, and Cayeux-sur-Mer. In summer, spaces can fill up quickly, so early arrival is recommended. Many walking and seal-watching trails begin from designated parking areas like Le Hourdel and the Marquenterre Park.

Dining

Seafood dominates the menus in the Baie de Somme. Expect platters of oysters, mussels, scallops, and grey shrimp, often served with a glass of crisp white wine. In Saint-Valery, La Table des Corderies offers fine dining with a bay view, while Le Mathurin and Le Café de Jeanne provide excellent brasserie-style options.

In Le Crotoy, Le Carré Gourmand and Les Tourelles are favourites for local fish dishes, and Au Petit Relais in Noyelles-sur-Mer is worth a stop for hearty regional cuisine. Be sure to try salicornes (samphire), often served as a salty, crunchy side dish or salad.

Shopping

Local markets are the best place to pick up regional produce, including salt marsh lamb, Picardy cider, honey, and artisanal soaps. Saint-Valery-sur-Somme holds a popular Sunday market, and Le Crotoy hosts its market on Fridays. For souvenirs, check out local art galleries, soapmakers, and food shops selling terrines, sea salt, and preserves.

When to Visit

The best times to visit the Baie de Somme are spring (April to June) and early autumn (September to October). These seasons offer mild weather, fewer crowds, and ideal conditions for wildlife watching. Summer is also lovely but can be busier, particularly during school holidays.

Winter is quiet and moody, with big skies and a stark beauty all of its own. It’s perfect for photographers and those who enjoy windswept walks, though some attractions and restaurants may be closed or have reduced hours.

Local Events

The Festival de l’Oiseau et de la Nature in April is a major event, celebrating birdlife and nature with excursions, photography exhibitions, and workshops throughout the bay. In summer, the Festival Art, Villes & Paysage places contemporary art installations in the hortillonnages and marshes, blending landscape with creativity.

Seasonal food festivals, flea markets, and village fêtes also pop up throughout the year in the region’s towns and hamlets.

Exploring Beyond Baie de Somme

From the bay, you can easily explore the inland Somme Valley with its WWI memorials and museums. Amiens, with its soaring cathedral and floating gardens, is less than an hour away. To the north, the cliffs of the Côte d’Opale offer dramatic coastal walks, and to the south, the forests and valleys of Normandy begin to unfold.
