The Alvor Estuary is a critical bird-watching site, frequently hosting flamingos and spoonbills in the protected wetlands adjacent to the beach.
The wooden boardwalk is built on stilts to protect the delicate dune ecosystem and prevent erosion from foot traffic.
The western end of the beach features a series of limestone sea caves and rock arches known as the Prainha or Três Irmãos rocks.
Geologically, the area is part of a sedimentary basin that features soft, Miocene-era calcarenite cliffs prone to natural weathering.
The Alvor river mouth serves as a vital nursery for various fish species, contributing to the local artisanal fishing industry.
Praia de Alvor is a multi-kilometer stretch of sand extending west from the mouth of the Alvor River estuary to the neighboring cliffs. The coastline features a wooden boardwalk system that spans over 3 kilometers, providing access across the dunes and marshland. The beach is characterized by its expansive golden sands and sheltered coves created by weathered limestone rock formations. It serves as a transition point between the urbanized Portimão area and the protected Alvor Estuary nature reserve. The beach consistently receives the Blue Flag eco-label designation for water quality and environmental management. Visitors can access a variety of beachfront restaurants serving traditional Algarve cuisine, particularly fresh grilled sardines and shellfish. The tidal nature of the estuary significantly alters the landscape, exposing extensive mudflats at low tide that serve as a habitat for local bird species. Beachgoers can walk from the eastern side of the beach toward the western 'Três Irmãos' cove section where the cliffs become more prominent.
