The area between the southeast of Portugal and the west of Andalucia keeps one of the largest reserves of copper in the world. The river Odiel is located in the middle of Huelva’s mining area, a piece of Mars on Earth.

A walk of colours
Huelva’s mining area

The river Odiel is the longest in Huelva province with 150 kilometres. The source is located in Sierra de Aracena and the mouth by Huelva City where the Odiel and the river Tinto confluent off to enter the Atlantic.

The gold and silver of Huelva’s mines attracted Phoenicians, Greeks and then Romans to the mythical land of Tartessus. This millennial mining activity has transformed the river as well as the environment, staining the water and the rocky slopes where it goes through with red, yellow and green colours.

Come with us to enjoy one of the most impressive walks in Andalucia!


We start our walk from the road that connects the mining towns of Calañas and Zalamea La Real to pass through plantations of eucalyptus and pine trees by the edge of the river. On our gradual way downstream we see old mills that used to be essential in the past for the area. Then, the path joins the old railway crossing mining kilns and spoils until we reach to recently re-open mine of Sotiel Coronada by the beautiful Roman bridge.
