Sol de Mañana, Geothermal field in Potosí Department, Bolivia
Sol de Mañana is a geothermal field in the highlands of the Potosí Department in Bolivia, where steam vents, mud pools, and fumaroles cover a wide stretch of open ground. The site sits at around 16,400 feet (5,000 meters) above sea level, making it one of the highest geothermal areas in the world.
After the energy crisis of the 1970s, Bolivia began studying the geothermal potential here as a way to reduce dependence on fossil fuels. Those early investigations drew scientific attention to the area and laid the groundwork for later research projects.
The communities of Quetena Grande and Quetena Chico consider this geothermal field part of their ancestral land. Visitors can sense this connection in the way the area is treated with care by those who live nearby.
A local guide is necessary to move safely around the site, as the ground can be unstable and hazards are not always visible. Visitors should dress warmly, since the altitude means temperatures stay low even on sunny days.
The name Sol de Mañana means 'morning sun' in Spanish, and early morning is indeed when the steam rising from the vents stands out most clearly against the cold air. Arriving at dawn gives a very different experience from a midday visit, when sunlight changes how the vapors appear.
