Machachi is the canton seat of Mejía Canton in the Pichincha province of Ecuador.
Machachi is located to the south of the capital of Ecuador, Quito. It is a city surrounded by the volcanos Atacazo, Corazon, Rumiñahui, Illinizas Peaks, Viudita Hill, Pasochoa, and Sincholagua, and owns part of the Cotopaxi volcano, a great active volcano which measures 5,897 m (19,347 ft) in altitude. In fact, the valley owns eight volcanoes inside, one the reasons Alexander von Humboldt named the region "Avenue of Volcanoes".
In the Panzaleo language, it means great active land. Machachi is the cradle of many slopes and the same ground is a perennial thermal and mineral water outcrop. In the fertile valleys of San Pedro are about 22 sources of chemicals which have theurapeutical properties.
