Pastaza is a province in the Oriente of Ecuador located in the eastern jungle. The capital is Puyo, founded on May 12, 1899 and which has 36,700 inhabitants. The city is now accessible by paved roads, a recent development; the main road from Baños follows the Pastaza river into the province.
The Pastaza River surges into the province from the west and as the landscape flattens, meanders on to the Napo, a tributary of the Amazon. Natural resources of Pastaza are bananas, grapefruit, tobacco, cocoa and coffee. Tea has successfully been cultivated by a few British companies, and in the mid-1980s one of the companies was honored by a visit from Princess Margaret from the royal family of Britain.
The landscape is mostly mountainous in the western part of the province and becomes relatively flat toward the east as it nears the Peruvian border with rivers and plains characterizing most of the province. The highest elevation is 1,820 meters. The climate is warm and humid due to the almost 7 meters of annual rainfall in the parts closest to the western mountains, but with significant amounts of rainfall throughout the province. The median temperature is 18 to 24 Celsius.
