Koh-Lanta: Raja Ampat

 was the 11th season of the French version of Survivor, Koh-lanta. This season takes place in Indonesia on the archipelago of Raja Ampat Islands, and will broadcast on TF1 in September 2011, every Fridays at 8:45pm (7:45 p.m. GMT) before Secret Story 2011 (France). Two new rules were introduced in this season. One is taken directly from the American Survivor format: the hidden immunity idol (represented as a collar), and a new rule called the black vote, which permits to an eliminated contestant to take revenge by voting one more time against one of the remaining contestants.
