Manzanares River

The Manzanares River is a river in Madrid, Spain, now newsworthy due to two distinct issues. Firstly, in late 2025, a highly pathogenic strain of avian influenza has caused the deaths of over 1,000 birds along its banks, prompting concerns and calls for carcass removal. Secondly, the river and its surrounding area, specifically Madrid Río park, are now part of free audio guide tours launched by the Madrid City Council. These tours, available in multiple languages, aim to educate visitors about the historical, cultural, and environmental significance of the area, along with other parks like El Retiro. The river's relevance is highlighted by both the ecological crisis and its integration into Madrid's tourism and recreational offerings.
