Sol de Mañana is an area with geothermal manifestations in southern Bolivia, including fumaroles, hot springs and mud pools. It lies at about 4,900 metres (16,100 ft) elevation, south of Laguna Colorada and east of El Tatio geothermal field. The field is located within the Eduardo Avaroa Andean Fauna National Reserve and is an important tourism attraction on the road between Uyuni and Antofagasta. The field has been prospected as a possible geothermal power production site, with research beginning in the 1970s and after a pause recommencing in 2010. Development is ongoing as of 2023.
