The park was created through a major urban renewal project initiated in the late 1990s to rehabilitate a severely polluted riverbed.
The site includes an artificial wetland area specifically designed to improve water quality through natural filtration.
It is part of a larger network of metropolitan green spaces managed by the Barcelona Provincial Council (Diputació de Barcelona).
The project received the Dubai International Award for Best Practices to Improve the Living Environment in 2002.
During heavy rainfall, the lower flood-prone paths may be closed temporarily for safety as the river level rises.
The park serves as a critical biological bridge connecting the Collserola mountain range to the Mediterranean coastline.
Parc Fluvial del Besòs is a 5-kilometer ecological restoration project connecting the municipalities of Barcelona, Santa Coloma de Gramenet, and Sant Adrià de Besòs. The park occupies the final stretch of the Besòs River before it flows into the Mediterranean Sea. It serves as a green corridor featuring a dual-path system designed for pedestrians on the lower level and cyclists on the upper level. The area is a reclaimed landscape that transitioned from a degraded industrial dumping ground to a functioning wetland habitat. It functions as a flood-mitigation zone during periods of heavy rainfall. The park encompasses approximately 115 hectares of riparian vegetation and accessible public space. Birdwatchers frequently use the site to observe species such as herons, egrets, and cormorants. The terrain is largely flat and paved, suitable for light exercise and commuting.

Bring a hat and sunscreen as there is very little natural shade along the riverbed paths.
Use the upper path if you prefer a view of the surrounding urban landscape, or the lower path for closer proximity to the water and vegetation.
Carry a water bottle as amenities are spaced far apart along the 5km stretch.
Do not attempt to walk in the lower paths if there is a flood warning or heavy rainfall, as the river can rise rapidly.
The lower paths may be closed periodically for cleaning or due to high water levels following heavy rain.
Cyclists must yield to pedestrians; keep dogs on a leash in designated areas.
