Ask any Spanish schoolchild where the Ebro River begins and they’ll tell you: Fontibre, in Cantabria. But science tells a slightly different story. In 1987, a team of technicians poured dye into a river in the Campoo region and waited to see where it would turn up. What they found changed the answer to a question that seemed settled: where does the most important river in northeastern Spain really begin?<\/strong><\/p>\n\n\n\n

In this deep dive, we’ll show you what the Fontibre spring looks like, what happened in that experiment, what you can visit at the Ebro River Interpretation Center, and where to eat gluten-free nearby, in Reinosa.<\/p>\n\n\n\n
