West of Portimão the coast opens into the Ria de Alvor: a protected estuary lagoon where the Alvor and Odiáxere streams braid through marsh, dune and sandbank to the sea — a Natura 2000 wetland that birds use as their Algarve hub.
The classic approach is the Alvor boardwalk: kilometres of timber walkway looping from the village over marsh and dunes to the long ocean beach, flat, free and superb at golden hour. Flamingos, spoonbills, storks and waders work the channels (winter and migration are best); kayaks and SUPs thread the lagoon from the village quay.
Alvor itself — a white fishing village with a working quay, Manueline church portal and seafood lanes — anchors the visit ten minutes from Portimão's centre.

History & context
The estuary fed Alvor's fishermen and salt workers for centuries — the village predates the Reconquista and kept its Manueline church through the 1755 tsunami; protection as a Natura 2000 site now keeps the lagoon working for the birds.
