The delta contains the Cal Tet lagoon, the largest remaining water body in the natural area.
It serves as a primary nesting ground for the Audouin's gull, a vulnerable Mediterranean species.
The area is strategically located directly beneath the flight paths of Barcelona-El Prat Airport, creating a unique juxtaposition of nature and aviation.
The delta's hydrology is heavily managed via sluice gates and canals to maintain water quality and prevent flooding.
The terrain is entirely flat and near sea level, making it susceptible to shifts in coastal erosion.
The site acts as a biological corridor connecting the Garraf Massif to the coastal sea area.
The Llobregat Delta is a protected wetland ecosystem situated at the mouth of the Llobregat River, serving as a vital stopover for migratory birds. The area comprises diverse habitats including marshes, pine forests, sandy beaches, and coastal lagoons. It functions as a critical green lung adjacent to Barcelona's urban and industrial infrastructure. The delta hosts the Remolar-Filipinas and Cal Tet nature reserves, which feature observation towers and walking trails. It is a designated Special Protection Area for birds (SPA) within the European Natura 2000 network. The landscape is shaped by the interplay between the river's sedimentation and the Mediterranean Sea.

Bring high-quality binoculars, as the best birdwatching spots are often at a distance from the main paths.
Carry sun protection and insect repellent, as shade is minimal and the wetlands attract mosquitoes in warmer months.
Stick strictly to marked trails to avoid damaging protected nesting habitats.
Do not attempt to walk onto the restricted beach areas during nesting seasons, as these are fenced off for conservation.
Some reserve sectors may have restricted access during peak nesting seasons; check local signage upon arrival.
Maintain silence to avoid disturbing wildlife; dogs must be kept on a leash or are prohibited in specific reserve zones.
