Koh-Lanta is a popular French reality television show that first aired in 2001. The program features contestants who are stranded on a remote island, where they must compete in various physical and mental challenges. The goal is to outlast other participants and avoid elimination, ultimately aiming to win a cash prize. Each season of Koh-Lanta typically includes a diverse group of contestants, often referred to as "adventurers." They form alliances, strategize, and participate in tribal councils to vote off their competitors. The show emphasizes survival skills, teamwork, and social dynamics in a competitive environment.
