Salgados Lagoon: Free Birdwatching at the Coastal Wetland Between Silves and Albufeira
They’re impossible to miss — great pink flamingos wading through shallow water, their curved necks sweeping for brine shrimp, wings flashing coral-red in flight. And you don’t need a boat tour, a guide, or a single euro to see them.
Salgados Lagoon (Lagoa dos Salgados) is the Algarve’s most accessible coastal wetland. Located between Silves and Albufeira, this shallow lagoon supports hundreds of flamingos year-round, plus dozens of other bird species that migrate through in spring.
Right now, in late March, the lagoon is at its best. Flamingos are resident year-round, but spring brings additional species — waders, terns, and ducks — that stop here during migration. The boardwalk is free, accessible, and perfect for a morning or afternoon nature walk.
What Makes Salgados Special
This isn’t a major wildlife reserve like Ria Formosa, but that’s precisely its appeal. Salgados offers:
Accessibility
A wooden boardwalk runs from the Praia Grande parking area directly to an observation platform overlooking the lagoon. The path is flat, wide, and suitable for wheelchairs, prams, and anyone with mobility limitations. No hiking required — you can see everything from the boardwalk.
Flamingo Paradise
The lagoon supports one of the Algarve’s largest flamingo populations. These magnificent birds are present year-round, but they’re most visible in the shallow areas near the boardwalk. In spring, expect to see:
- Dozens to hundreds of flamingos feeding
- Juvenile birds (grey, taking two years to turn pink)
- Flocks taking flight — a spectacular pink cloud
Migration Bonus
Spring brings additional species passing through:
- Greater flamingos (resident)
- Little egrets
- Grey herons
- Black-winged stilts
- Kentish plovers
- Common terns (in summer)
- Sandwich terns
Location: The lagoon sits between the EN125 road and the Atlantic coast, directly adjacent to Praia Grande (Guia beach). It’s part of the wider Ria Formosa coastal system, though geographically separated.
The Walk: Boardwalk Trail
Distance: ~2 km out-and-back | Elevation: Flat | Difficulty: Easy
Time: 1-1.5 hours | Best season: Year-round, March-May for migration
Getting There
From the EN125 between Silves and Albufeira, follow signs to “Praia Grande” or “Lagoa dos Salgados.” There’s a large free parking area at the beach (arrive early on weekends for a spot).
By public transport:
Faro Airport is about 30 minutes away. You can take a bus from Faro to Guia or Alcantarilha (via EVA bus company), then walk 15 minutes to the lagoon. Having a car is much easier.
Parking:
Free at Praia Grande car park. The boardwalk starts from the northern end of the parking area.
The Boardwalk
The wooden boardwalk is straightforward — a straight path leading to an observation platform. There are no branches or variations:
Section 1: Parking to Mid-point (500m)
The path crosses dune vegetation. In spring, you might see:
- Crested larks in the scrub
- Common swifts overhead
- Yellow wagtails near the water
Section 2: Mid-point to Platform (500m)
As you approach the water, birds become more visible. The shallow areas are where flamingos feed. Bring binoculars — some birds are distant, but the flamingos in the near channels are spectacular.
Observation Platform:
The end of the boardwalk offers panoramic views of the lagoon. This is where most visitors stop. On busy summer days, it can get crowded; in late March, you’ll likely have space.
What You are Seeing: Late March
Primary Species:
- Greater Flamingo: The star. Pink, tall, unmistakable. Look for the black flight feathers visible in flight. About 200-400 present year-round.
- Little Egret: Small white heron, black legs with yellow feet. Often hunts near the flamingos.
- Grey Heron: Larger, grey heron standing sentinel at the water’s edge.
- Black-winged Stilt: Elegant wader with impossibly long pink legs. Present in small numbers.
Possible Migrants (March-April):
- Glossy Ibis: Dark, iridescent ibis occasionally seen
- Ruddy Turnstone: Rocky shoreline near the beach
- Sandwich Tern: Summer visitor, arriving in April
Surrounding Area:
The adjacent Praia Grande beach is one of the Algarve’s longest. After your birding walk, you can combine with a beach walk or swim (water temperature ~16°C in March — bracing!).
Practical Tips
When to go:
- Early morning (7-9am): Best for bird activity, calm conditions, fewer people
- Late afternoon (4-6pm): Good light for photography, flamingos still active, potential sunset over the lagoon
What to bring:
- Binoculars (essential — many birds are at distance)
- Camera with zoom (200mm+ helpful for wildlife)
- Sun protection (limited shade on boardwalk)
- Water (no facilities on the boardwalk)
- Layers (windy on the coast, even in spring)
Conditions:
- Boardwalk is wheelchair accessible
- No dogs allowed on the boardwalk (beach is dog-friendly in some sections)
- No food vendors at the lagoon — bring snacks
- Beach facilities (toilets, showers) at Praia Grande car park
Seasonal note:
- March-May: Best overall — resident flamingos plus migration species
- June-August: Fewer birds, more people, but beach is popular
- September-November: Migration again, fewer crowds
- December-February: Resident species only, quiet
Local tip: Combine with the beach — Praia Grande is one of the best in the central Algarve, with dramatic cliffs and wide sand. Make a morning of it.
Why It is Free
The boardwalk and observation platform are maintained by the municipality of Lagoa. The lagoon itself is a public wetland area. No entrance fees, no guided tours required, no commercial boat operations — just walk out and look.
