The Ria Formosa Natural Park is one of Portugal's most distinctive landscapes — a 18,400-hectare lagoon and wetland system stretching for 60 kilometres along the eastern Algarve coast, from Faro east to Vila Real de Santo António. The park consists of four sandy barrier islands and two peninsulas that form a natural bulwark protecting an inner lagoon of channels, salt marshes, mudflats, and salinas (working salt pans) from the Atlantic. Recognised as one of the Seven Natural Wonders of Portugal, it has been a protected Natural Park since 1987 (upgraded from its earlier Nature Reserve status).
For birdwatchers, Ria Formosa is one of the most important wetlands in southern Europe. Over 200 bird species have been recorded here, and around 30,000 birds can be observed at any one time during peak migration seasons. Pink flamingos congregate in the salt pans throughout the winter and increasingly stay year-round; herons, terns, spoonbills, gulls, and migratory waders fill the lagoons. The park is also one of the last European breeding grounds for several threatened bird species.
Beyond birds, Ria Formosa is home to the world's largest population of seahorses (estimated at around 1.5 million individuals in the early 2000s, though declining due to habitat pressure), the rare Mediterranean chameleon (one of only two reptile species of its kind in mainland Europe), and abundant marine life that supports the local fishing and shellfish economy — the inner lagoon is one of Portugal's most important sources of clams, oysters, and razor clams.
For visitors, the park can be experienced in several ways. Boat tours from Faro Marina explore the channels and barrier islands (typically 1.5–3 hours, €15–€35 with operators like Formosamar). Land-based exploration is possible at the Centro de Educação Ambiental de Marim near Olhão (the park visitor centre, with self-guided trails), and the barrier islands of Faro, Culatra and Armona are reachable by regular ferry. Free public access throughout.

History & context
The Ria Formosa lagoon has been a working environment for human communities since prehistoric times. Salt extraction in the inner lagoon dates back to Roman times, when the surrounding villas at Milreu and elsewhere produced salt for fish-preservation industries that supplied the wider Roman world with garum (fermented fish sauce) and salted fish. The system of artificial salinas — shallow rectangular pans where seawater is evaporated to crystallise salt — has been continuously worked for at least 2,000 years.
Throughout the medieval and early modern periods the lagoon supported fishing communities on the barrier islands and along the coast, with shellfish and salt as the principal exports. The 20th century brought intensification of agriculture along the lagoon margins, the development of tourism on the barrier islands (especially Praia de Faro), and significant environmental pressure from urban development.
In response, the area was first protected as a Nature Reserve in 1978 and then upgraded to Natural Park status in 1987 — a stronger classification that brought tighter limits on construction, fishing, and human use. The park is managed by ICNF (Instituto da Conservação da Natureza e das Florestas), the Portuguese conservation authority, and recognised internationally as a Ramsar Wetland of International Importance and a Special Protection Area under the EU Birds Directive.
In 2010 the Ria Formosa was voted one of the Seven Natural Wonders of Portugal in a national poll, alongside other landscapes like the Berlengas Islands and the Madeira Laurissilva. Today the park hosts around 1.5 million visitors a year — a sustainability challenge that the management authority addresses through controlled access, visitor centres, and ongoing habitat restoration.

Preguntas frecuentes
What's the best way to experience Ria Formosa?
Three main options. (1) A boat tour from Faro Marina — typically 1.5–3 hours, €15–€35, covering the main channels and one or two barrier islands; operators include Formosamar, AnimaRis, and Lands. (2) Self-guided walking at the Centro de Educação Ambiental de Marim near Olhão (the park visitor centre) — free entry, marked trails through wetlands and a tide mill. (3) Take a regular ferry to one of the barrier islands (Culatra, Armona, or Ilha de Faro) for a beach + lagoon day.
Where can I see the flamingos?
Flamingos congregate in the salt pans (salinas) along the lagoon, particularly between Faro and Olhão. The Quinta de Marim trail near Olhão and the Ludo salt flats near Faro Airport are reliable spots. Best season: winter (November–February) when flamingo numbers peak, but increasing numbers stay year-round. Boat tours often pass close enough for good viewing; bring binoculars.
How do I get to the park from Faro?
The park literally borders Faro — the lagoon starts at the city's marina. Boat tours leave directly from Faro Marina (5-minute walk from the centre). For the visitor centre at Quinta de Marim, drive 10 km east to Olhão (15 min) or take the train. For Ilha de Faro / Praia de Faro, take bus 14 or 16 from Faro bus station (20 min). The whole park is accessible without a car if you use ferries, buses, and trains.
When is the best time of year to visit?
Spring (March–May) and autumn (September–November) are ideal — mild weather, peak bird activity, and fewer tourists than midsummer. Winter (December–February) is the peak flamingo season but the lagoon can be windy and cool. Summer (June–August) is great for beach days on the barrier islands but the inner lagoon channels can be hot and busy. Boat tours operate year-round.
Is the park accessible for wheelchairs?
Some sections, yes. The Quinta de Marim visitor centre has accessible paths and a wheelchair-friendly trail through part of the wetland. Boat tours vary by operator — confirm in advance. Beach access on Praia de Faro is partially accessible via the boardwalk; some ferries to barrier islands have accessibility limitations. Plan ahead by contacting the park or your chosen operator.
