The Huallaga Valley is located in northern Peru, south of Tarapoto. It follows the Huallaga River.
Since the 1980s, the primary coca growing and drug trafficking activities in Peru have been in the Upper Huallaga Valley. [1]
The coca is flown to Colombia, where it is used to create cocaine, which is subsequently shipped to the United States.
Vladimiro Montesinos, ex-head of Peru's intelligence service, is reported to have received $50,000 for every plane laden with drugs allowed to leave the Huallaga Valley. [2]
