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.

After walking in the footsteps of the Romans, who left behind an exceptional architectural heritage, the two contestants, Pauline and Fabrice, will cross the Camargue — a wild land where earth and water shape landscapes home to a rich variety of flora and fauna. Their quest will also be an opportunity to follow in the footsteps of some of the world’s most famous artists who found inspiration in Provence.

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.
