Termas del Flaco is a hot springs resort with thermal baths at an elevation of 1.776m above the sea level located in the Región del Libertador Bernardo O'Higgins, of Chile.
The baths, also known as Baños del Tinguiririca and Las Vegas del Flaco, are located in the Colchagua valley, in the Andes mountain range. The road is one-lane and dicey, as it follows the tumbling Tinguiririca River upstream, and leading eastward into the Chilean Andes. This long gravel road is called I-45. Starting from San Fernando, on the Panamericana Sur 64, the drive is 77.8 km long, with no pavement, that can be covered by any type of vehicle. The dirt road to the baths is only open from December to April and closed from May to November. It’s usually closed in winter time due to heavy snow.
