Although there are many geysers along the Andes Mountains, in Argentina there is only one destination where these natural formations can be observed, and it is located in the province of Neuquén.

Walking among the Los Tachos geysers means stepping into one of the most surprising and little-known geothermal phenomena of Argentine Patagonia, where the earth seems to be alive. Located in a volcanic area near the Copahue region, these geysers expel steam, gases and hot water from underground, creating a steaming, dynamic landscape with an almost extraterrestrial appearance. The constant bubbling of the water and the sound of steam emerging from the ground turn the walk into a unique sensory experience.

The geysers of Neuquén formed in the northern part of the province, in an area near the Domuyo Volcano, identified as the highest point in Patagonia at 4,702 metres above sea level. Thanks to the volcanic activity of the area, the rocks created four openings capable of expelling powerful jets of water and steam at an average temperature of 90°C.

The route takes place at high altitude, in a rugged environment dominated by volcanic rocks, mineral soils and thermal emissions. In some sections, the steam reduces visibility and the smell of sulphur becomes noticeable, reinforcing the sensation of being in a primitive and powerful place.

The activity requires caution, as the terrain may be unstable and the temperatures of the water and steam are very high. It is an ideal adventure for those seeking to explore extreme landscapes and understand volcanic activity up close.
