The Valle de Colchagua wine region is 130 kilometers south of the Chilean Capital city of Santiago de Chile in the Valle Central. Together with the similar area Cachapoal it forms the southern half of the Valle de Rapel region. The center is the city of Rancagua, known for its hot thermal springs. Colchagua is traversed by the Río Tinguiririca, which is the only way to make wine. The Mediterranean, hot climate is tempered by cool air currents from the Pacific Ocean to the west.

A wine tourist attraction is the “Tren del Vino” train, which runs on steam locomotives and travels through the wine fields.
