Tranquilandia was the name of the large cocaine processing laboratory located in the jungles of Caquetá, Colombia. Tranquilandia was constructed for the Medellín Cartel by José Gonzalo Rodríguez Gacha, also known as the Mexican. Until its destruction in 1984 by the Colombian National Police assisted by the United States Drug Enforcement Administration (DEA), the complex consisted of 19 laboratories, an independent water and electrical system along with dormitories for the laboratory workers. Processing supplies were flown in, and processed cocaine was flown out via any one of eight airstrips, constructed by the cartel, for that specific purpose.
