Tagus Estuary Natural Reserve

The Tagus Estuary Natural Reserve is a protected wetland area along the river near Setúbal, featuring mudflats, salt marshes, and shallow waterways. Salt ponds and agricultural fields intersperse throughout, creating a mosaic landscape where water and land constantly shift.

The government designated this area as a protected reserve in 1976 to safeguard Portugal's largest wetland system. This action recognized the region's importance for wildlife migration and the health of river ecosystems.

Salt production in the ponds relies on methods that families have practiced for centuries, shaping how the land is organized and used. Visitors can observe how this work connects people directly to the rhythm of the seasons and the water cycle.

The best time to visit is during migration seasons when bird populations peak, though the area remains active year-round. Walking trails and viewing platforms are marked and easily accessible, making navigation straightforward for most visitors.

Winter months bring around 120,000 water birds to this location, including a large portion of Europe's pied avocet population that stops here during migration. This concentration makes the reserve one of the continent's most important sites for bird watching.
