Besòs, Mediterranean river in Barcelona Province, Spain
The Besòs is a river in Barcelona Province that flows from the junction of the Mogent and Congost rivers toward the Mediterranean. It passes through a large green space with pathways and planted areas that extend across multiple neighborhoods.
The waterway suffered severe pollution during the 1970s and 1980s and became known as one of Europe's most contaminated rivers. A major restoration effort starting in 2004 aimed to reverse this damage and transform it into a public green space.
The riverbanks have become gathering places where residents spend time walking, cycling, or enjoying moments with family across multiple neighborhoods. These pathways create connections between different communities and form a shared space for everyday activity.
The riverbanks have well-maintained walking and cycling paths with access points from different neighborhoods. Spring and autumn offer the most comfortable conditions for a visit, with moderate temperatures and fewer crowds.
The restoration of the waterway involved removing high-voltage infrastructure and creating wetland areas that now support hundreds of bird species. This recovery demonstrates how a severely damaged site can become a valuable habitat once again.
