Survivor: Cook Islands is the thirteenth season of the American competitive reality television series, Survivor. The season was filmed from June 26 to August 3, 2006, and premiered on September 14 of that year. Filmed in the Cook Islands, it was broadcast by CBS. The season had 20 contestants who were initially divided into four "tribes" by ethnicity: African American, Asian American, Hispanic American, and Caucasian. The tribes were named after some of the Cook Islands: Manihiki, Puka Puka, Aitutaki, and Rarotonga. They were later merged into a single tribe, Aitutonga. The season was the first with a final consisting of three participants, rather than two. Yul Kwon defeated Ozzy Lusth and Becky Lee by a jury vote of 5–4–0 and was named the Sole Survivor, winning $1,000,000. Overview Survivor is a reality television show based on the Swedish show Expedition Robinson, created by Mark Burnett and Charlie Parsons. The series follows a number of participants isolated in a remote location, where they must provide food, fire, and shelter. One participant is removed from the series by majority vote every three days, with challenges held to give a reward (ranging from living- and food-related prizes to a car) and immunity from being voted out of the series. The last remaining player receives a prize of $1,000,000. Pre-production began in spring 2006, and principal photography lasted from July 3 to August 11, 2006. Filming locations The tribal camps, Exile Island, and many of Survivor: Cook Islands challenges were filmed on motu (islets) in the Aituaki lagoon. The Rarotonga (later Aitutonga) tribe's camp was on Moturakau, and the Aitutaki tribe lived on Motukitiu. The short-lived tribes of Manihiki and Puka Puka lived on Rapota and Muritapua, respectively. Most challenges were filmed on Tekopua and Tapuaetai (One Foot Island). Exile Island is a small sand cay south of Tapuaetai, and the bow of the wooden ship was brought in for the show. West of Tapuaetai is another sand cay, called "Nude Island" by locals because of its lack of vegetation. The third challenge was staged in the shallow water just off the shore of Nude Island. Akaiami hosted challenges and "The Ponderosa," where eliminated contestants remained until the end of the game. The Tribal Council, the production camp, and a few challenges were located on the main island of Aitutaki. There were three reward trips to the neighboring islands of Atiu, Mitiaro, and
