With summer comes the return of "La Carte aux Trésors". In this episode, the spotlight is on the Maurienne Valley, located in the Auvergne-Rhône-Alpes region. The game area will stretch along the Arc River, which runs through the Maurienne Valley, between the Vanoise Massif to the north and Italy and the Col du Galibier to the south, passing through Saint-Jean-de-Maurienne, Modane, and Bonneval-sur-Arc. The two contestants, Charlotte and Najim, will have to solve riddles to discover the Treasure and take part in a giant treasure hunt that will lead them to majestic landscapes where thrill-seekers defy the laws of balance. They will also enjoy a famous fondue that contributes to the culinary reputation of Maurienne and the Savoie region.

In this episode, the game area will stretch across the southern part of the Massif Central, from the Aubrac plateaus to the Cévennes, passing through the Lot Valley, Marvejols, Mende, and the Tarn Gorges. The two contestants, Laure and Julien, will have to solve riddles to discover the Treasure and embark on a giant treasure hunt that will lead them to encounter unusual animals from around the world. They will also explore the mineral world — as fascinating as it is mysterious — buried deep within the earth. Along the way, the lakes of the Aubrac and its landscapes will remind them of the Irish plains or Canadian forests.

Heading to the Bay of Quiberon and its surroundings, a jewel of Southern Brittany with breathtaking landscapes: wind-swept cliffs, sandy beaches, and charming villages. The game zone stretches from the Etel estuary in the west to the gates of the Gulf of Morbihan in the east, passing through Carnac, Locoal-Mendon, and the island of Hoëdic. The two contestants, Marine and Daniel, will have to solve riddles, find capsules, and face challenges in this stunning setting in hopes of winning the Treasure. They set off to discover a sublime heritage shaped by oyster farmers, and the small houses that give this region—where land and sea sometimes blend—their unique charm.

Cyril Féraud and the entire team head to Calvados to explore the treasures of the Côte Fleurie and the Pays d'Auge. The game zone stretches from Cabourg in the west to the mouth of the Seine in the east, passing through Lisieux and Honfleur, in a setting that blends majestic beaches, picturesque villages, and lush green valleys. The two contestants, Lauren and Kévin, will have to solve riddles to find the Treasure and travel across this emblematic region in a life-sized treasure hunt. This adventure includes an introduction to an unusual equestrian discipline in a land where horses reign supreme, an investigation around an invisible yet essential line in daily life, and a heritage hunt through the most beautiful villages of the Pays d'Auge.

Cyril Féraud and the whole team head to Meurthe-et-Moselle. The game area stretches along the Moselle River, from Briey in the north to Baccarat in the south, passing through Pont-à-Mousson, Nancy, Toul, and Lake Pierre-Percée. The two contestants, Adélaïde and Vianney, will have to solve riddles and take on challenges to find the famous hidden capsules scattered across this vast area, in hopes of reaching the Treasure. On the agenda for this new adventure: visits to exceptional places where fire transforms matter, showcasing the region’s proud glassmaking and ceramic craftsmanship; a dive into Nancy, birthplace of Art Nouveau; and an exploration of the vast fortifications built before the First World War — remnants of a defensive system that was, in its time, the largest in the world.
