The Peña del Hierro Viewpoint, located in Nerva (Huelva), is part of the Riotinto Mining Park and offers one of the most impressive views of the source of the Tinto River, as well as the mining crater of the old pyrite mine.

The source of the Tinto River is located in the municipality of Nerva, in the province of Huelva, Andalusia, and is one of the most unique landscapes in Europe due to its reddish color and its scientific and geological value.

The great extension of its lakes, the abundance and variety of formations, and the length of its development make this underground complex a complex of great beauty and showiness. This spring of inexhaustible beauty, forged by time on nature itself with the help of elements as simple as water and stone, offers an exceptional set of galleries, halls, lakes and underground courses.

To get to the viewpoint, paid access is required. The hiking trail ends here at a fence. Nevertheless, a somewhat limited view of the opencast mine is possible

An approximately 3 kilometer long circular route leads around the natural monument Montera de Gossan. Don't miss it because of the beautiful views.

Also known as the Padre Caro mountain range, it indicates the source of the Río Tinto which runs through the interior of Huelva for about 100 km until it reaches the Odiel River. 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.

Corta Atalaya was the largest open pit (mainly copper) mine in Europe and at one time the largest in the world. It has a roughly elliptical shape, 1,200 meters long, 900 meters wide and 350 meters deep.
