The GR®120, also known as the Coastal Trail, follows the coastline from Flanders to Normandy. Formerly used by customs officers to monitor the coasts, this trail offers hikers a unique experience, inviting them to discover the natural wonders of the dunes of Flanders, the Opal Coast, the Picardy Coast, and the Alabaster Coast. This coastal path crosses the French departments of Nord, Pas-de-Calais, Somme, and Seine-Maritime. It is accessible to hikers of all levels, as it does not present any particular difficulties. However, it should be noted that some sections may be impassable during high tides. It is therefore recommended to check the tide schedules before setting off. The profile of the GR®120 varies from 0 to 142 meters in altitude, but the majority of the route is relatively flat, making it accessible to all. The only sections with elevation changes are located near Cap Blanc-Nez and Cap Gris-Nez, as well as between Boulogne-sur-Mer and the final 15 kilometers before reaching Le Treport.

This trail offers a true journey through remarkable sites. It traverses the Westhoek, a region bordering France and Belgium, as well as the national nature reserve of Platier d'Oye. The Regional Natural Park of Caps and Marshes of Opal, home to the iconic site of the Two Caps, is also included in the itinerary. Hikers will also have the chance to discover the national nature reserve of the Bay of Canche, the national nature reserve of the Bay of Somme with its famous Marquenterre Park, and the marine nature park of the Picardy estuaries and Opal Sea. The GR®120 is easily accessible by train, as it passes by numerous train stations along the route. Hikers can start their adventure from departure points such as Dunkirk, Calais, Boulogne-sur-Mer, Le Touquet, and many others.

In conclusion, the GR®120 - Coastal Trail offers an unforgettable experience, allowing hikers to explore the fascinating coastlines from Flanders to Normandy. With its coastal landscapes, preserved nature reserves, and remarkable sites, this trail reveals the splendor and diversity of the French coastline. Whether you are an avid hiker or simply seeking a seaside adventure, the GR®120 promises an enriching and memorable experience.
