Koh-Lanta: L'Île au Trésor (transl. Koh-Lanta: Island of Treasure) was the sixteenth season of the French version of Survivor, Koh-Lanta. The main twist this season is that there is an island separated from the two tribes known as Treasure Island. On the island is a buried chest which contains the Golden Ring, an item which secures the owner a spot in the final five. In order to open the chest, the contestants must find ten metallic pieces, each of which points to the next marker. Once all ten pieces are found, the chest can be opened.
