What kind of terrain can I expect on the trail?

The trail offers a diverse coastal landscape. You'll walk through mudflats, salt marshes, and various dune types (embryonic, white, and grey dunes). Some sections might feature sandy paths, while others are natural walking trails or even boardwalks. You may also encounter humid meadows with freshwater ponds and parts of the beach.

What is the best time of year to hike this loop?

Trail Reviews

November 3, 2024, O4. Réserve Naturelle Nationale du Platier d'Oye

The last day of our trip we started with a visit to La Coupole. Here you learn everything about the V1 and the V2. The visit is pleasant with a tablet and a kind of treasure hunt, which you can't help but get carried away - even at our age 😀. During previous visits to the Opal Coast I had skipped the Coupole in favor of hiking, but on the advice of friends the Coupole was now on the program and we are glad we visited it. In the afternoon we went for a coastal and dune walk. Unfortunately the predicted warm weather didn't materialize. The Platier d'Oye is a nature reserve that we knew from our bike trip to Cherbourg. And squeezed between Dunkirk and Calais it is a small stretch of beach that belongs to the Land of St-Omers for Komoot.

Part of the path is closed at the reserve, which slightly modifies the route planned on the site. This walk suggests going along the beach for 3 km then branching off onto a dune path (sand) then continuing on a grass path and then a wooden path.
