Source of the Río Tinto

Highlight • River

Site also known as Sierra de Padre Caro. It marks the source of the Rio Tinto, which flows through the interior of Huelva for about 100 km until it reaches the Rio Odiel. Its name is due to the reddish color of its waters, caused by the weathering of minerals with a high content of heavy metal sulfides that were found and exploited in various deposits along the riverbed. This marvelous site and the river that originates here are the subject of scientific studies in collaboration with NASA to analyze a possible analogy with the planet Mars.
