Alvor Estuary Boardwalk

Park

The Alvor Estuary Boardwalk is a wooden walkway that winds through the salt marshes, mudflats and tidal channels of the Ria de Alvor, a protected wetland on the western Algarve coast between Portimao and Lagos. The boardwalk stretches for approximately two kilometres, raised on stilts above the marshes, and provides access to a habitat that would otherwise be impassable on foot.

The estuary supports a rich ecosystem. Glasswort, sea lavender and other salt-tolerant plants colonise the marsh surface, while the tidal channels teem with small fish, crabs and molluscs. Birdlife is abundant throughout the year: herons, egrets, spoonbills, avocets and flamingos feed on the flats at low tide, while ospreys hunt over the deeper channels. During the autumn and spring migrations, the estuary hosts significant numbers of passage waders including sandpipers, dunlin, godwits and plovers.

The boardwalk begins near the bridge on the EN125 and follows the northern edge of the estuary towards the sea. Interpretive panels identify the principal species and explain the ecological processes that maintain the marsh. The path is flat throughout and accessible to wheelchairs and pushchairs, making it one of the more inclusive nature walks in the region.

The best times to visit are early morning or late afternoon, when the light is softer and bird activity peaks. Low tide exposes the mudflats and brings the waders in to feed, while high tide pushes birds closer to the boardwalk for easier observation. The walk can be combined with a visit to the village of Alvor, a former fishing settlement with a lively restaurant quarter built around a sheltered harbour.
