The adjacent Lagoa dos Salgados is one of the most important birdwatching sites in the Algarve due to its status as a coastal wetland.
The beach acts as a physical buffer between the Atlantic Ocean and the freshwater marshland of the Salgados Lagoon.
The area is home to specialized dune flora, such as the European marram grass, which helps stabilize the shifting sands.
The beach is the western extension of the sands that stretch toward Armação de Pêra, though it retains a distinct, less developed character.
Praia Grande de Pêra Poente is a sprawling sandy beach situated between the mouth of the Alcantarilha River and the Armação de Pêra resort area. The beach is defined by an extensive, protected dune system that separates the coastal shore from the Lagoa dos Salgados lagoon. The lagoon serves as a significant stopover for migratory birds, including flamingos and purple swamphens. Due to the river mouth, currents can be strong, and the water depth increases relatively quickly compared to more sheltered bays. The beach is largely unserviced, offering a more rugged and natural environment than the nearby urbanized sections of the Algarve coastline. Walking trails traverse the wooden boardwalks that protect the fragile dune vegetation.

Use the wooden boardwalks to access the beach to avoid damaging the protected dune ecosystem.
Bring your own shade and refreshments, as facilities are minimal compared to the nearby main resort beach.
Check tide tables before visiting, as high tide can significantly reduce the available sandy area.
Do not attempt to swim in the Alcantarilha river mouth area due to unpredictable currents and changing sandbanks.
Maintain silence near the lagoon to avoid disturbing migratory birds; respect all fenced-off dune preservation areas.
