Further south, Cap Gris-Nez presents a completely different face, with dark rocks and viewpoints overlooking the continuous ship traffic in the strait. Hiking, photography, and contemplation are guaranteed here.

Your journey continues through the fishing villages. In Wissant, the atmosphere remains authentic and welcoming: the vast beaches are a paradise for kitesurfing enthusiasts. In Audresselles, time seems to stand still: small fishermen’s houses, colorful boats (flobart), and the majestic Fort Vauban, which has watched over the sea for centuries. Further south, Ambleteuse enchants with its Vauban-fortified fort, maritime heritage, and proximity to the wild nature of the dunes.

The D940 then leads you to the iconic seaside resorts of the Opal Coast tourism. Wimereux, with its colorful Belle Époque villas, is perfect for a stroll along the lively waterfront promenade. A culinary stop is recommended at the artisanal biscuit factory Sophie Farrugia, offering a wide range of sweet and savory treats without preservatives or additives. Specialties include butter cookies, filled waffles, meringues, macarons, rusk, and croutons – all with authentic local flavor.

In Boulogne-sur-Mer, immerse yourself in history with the fortified old town and discover Nausicaá, Europe’s largest aquarium, which delights both young and old with thousands of marine species from around the world. Further south, Hardelot attracts visitors with its long family beaches, a medieval castle, and expansive forests, perfect for hiking. The must-see Le Touquet - Paris-Plage awaits with its elegant seaside resort charm, shops, markets, Belle Époque villas, and a lively cultural and festive atmosphere.

Finally, stop in Berck-sur-mer, a well-known seaside resort with vast beaches, international kite festivals, and an impressive seal colony visible at low tide.

Your journey ends magnificently on the beautiful Opal Coast tourism in Saint-Valery-sur-Somme. This medieval village, listed among the “Most Beautiful Villages of France,” enchants with its cobbled streets, colorful houses, harbor, and breathtaking views of the bay. Nature reigns supreme here, with exceptional biodiversity and a timeless, peaceful atmosphere.

At every stop, the Opal Coast tourism and the Baie de Somme reveal their treasures. History enthusiasts will appreciate the forts and museums, while food lovers will not resist the local specialties: freshly caught fish and seafood, golden waffles, regional cheeses, and craft beers.
