Ameca Valley
The Ameca Valley, also known as the Ameca-Cocula Valley, is a valley and drainage basin situated in central Jalisco, Mexico. It is surrounded by mountain ranges of the Sierra Madre Occidental. The three main cities and municipalities of the valley are Ameca, San Martín de Hidalgo, and Cocula. The Ameca River and its smaller tributaries, such as the San Martín River, drain into the valley thus creating the Ameca drainage basin. The valley is part of the federal sub-division Región Valles, for which the city of Ameca serves as its seat.
