In the heart of the Andalusian Mining Basin, Viajar magazine has singled out the Tinto River Route as the premier choice for hikers in Huelva. This trail, stretching approximately 18 kilometers, is considered one of Spain's most spectacular and an essential experience for 2026.

The path follows the famous reddish river, largely tracing the old mining railway line. Visitors can delve into the region's industrial history, observing the remnants of mineral washhouses, breakwaters, and railway workshops that dot the route.

The most striking aspect of the route is its landscape, with the river's red waters and the ochre tones of the rocks creating a scene that evokes an almost Martian environment. This phenomenon is due to centuries of mining activity, which have uniquely colored the terrain in the peninsula.

One of the most notable points is the area around the Los Frailes halt, in El Campillo, where one can closely observe the unique course of the Tinto River and the intense ferruginous color of its waters. The sensory experience is completed by the silence of the surroundings and the metallic scent emanating from the river, transporting the hiker to another era.

The Tinto River is a site of global scientific interest due to the high acidity of its waters and the presence of extremophile microorganisms, conditions that resemble those that might exist on Mars. The route passes through part of the Tinto River Protected Landscape, a natural area that hosts one of Europe's most impressive mining landscapes, enriched with pine forests, tunnels, and old bridges.
