Termas Geométricas Hot Spring Complex collects its thermal waters at a temperature of 80ºC from more than sixty springs along a 500 meters long previously inaccessible ravine, in the midst of a native forest, at km 16 of the road that goes from Coñaripe to Villarrica Sur National Park. This beautiful world preserve was created in 2004 by Germán del Sol to make it possible for visitors to enjoy a bath at leisure in one of the eighteen stone pools filled with pure hot thermal water, in the midst of brutal nature, thanks to the help of architecture.
