The Algarve has a railway line that conveniently connects some excellent bird-watching sites. At least, they are good for bird-watching in winter, and for general wildlife and plants for most of the rest of the year.
We try, where possible, to take trips to places where there is good public transport to visit interesting sites. And while the Algarve Railway does not get us to ALL the good bird-watching sites, it provides enough to get through a two-week trip easily. If you have a bicycle, that will extend the distance you can cover easily from the train stations. And, of course, there are buses and taxis that will take you further.
Vila Real de Santo Antonio station
Situated at the very eastern end of the Algarve, this station gives access to the Guadiana River. Walking south, follow the road more or less alongside the river down to the break-water and navigation light at the entrance. This can be interesting in stormy weather with seabirds such as shearwaters and little terns passing close. Gulls follow fishing boats going in and out of the towns. At low tide there are often gulls and waders sitting out on sandbanks, or feeding in the silt.
The forest on the inland side of the road protects the town from sand blown in from the shore. It’s good for bird-watching – with crested tits, shrikes, gold and firecrests, among the attractions, and much more at migration time. The network of paths is used by athletes training at the nearby sporting complex, so expect to see a lot of joggers and cyclists too. You can meander through the forest, and/or along the beach and dunes, then end up at the station at Monte Gordo (it’s 1km north of the holiday village).
North of the Vila Real station is the traditional fishing harbour, which again provides options for viewing the river. Walk along the road on the north side of the tracks to overlook the saltmarsh and creeks of the Carrasqueira Creek. This is pretty good for waders at low tide, but anything can turn up at any time. On the west side of the main road, the creek broadens out and always holds water as it is more-or-less dammed by the road. Lots of coot – often hundreds in winter – along with grebes and other waterbirds spend the winter here. It’s also good for Caspian terns – I’ve seen one on most visits.
Reserva Natural do Sapal de Castro Marim e Vila Real de Santo Antonio
The official title is quite a mouthful, so it’s often just referred to as the Castro Marim reserve. The Carrasqueira Creek forms the southern boundary to this huge area of saltpans – some commercially active, others abandoned. The reserve also includes saltmarsh, fishponds and muddy creeks, bordered by pasture and orchards, and the town of Castro Marim itself.
From Vila Real, follow the busy main road north towards Castro Marim. Then it’s a relief to turn onto a track going west past ruined farm buildings. This is really the only official public access through the reserve away from the road. It takes you past the active saltpans to a minor road on the other side where you can walk south to the Castro Marim station, or north to Castro Marim town. There can be huge numbers of birds here, including flamingos and black-winged stilts. However, if the weather is calm and the tide is out, a good proportion of the birds will be feeding out at sea or on the Rio Guadiana margins. If the weather has been wet, the track can be very slippery, and the salty silt surface sticks to your shoes.
The reserve continues north-east of Castro Marim, but access is more limited. A south-facing pasture near the village is a good place for stone curlews and Iberian hares. Black-winged stilts, black-tailed godwits, curlew sandpipers and other waders feed or roost in the saltpans. There is a reserve information centre not far from the bridge across the Guadiana, but it is not always open. We took a taxi here from Castro Marim, and walked back along a track next to stone-pine plantations.

Conceição station serves the community of Cabanas de Tavira, which has a small holiday resort area next to the creeks at the eastern end of the Rio do Formosa Natural Park. You can walk through the town to reach the shore, and access the offshore sand-bars. Or you can follow the track eastwards on the south side of the railway line into the Tavira saltpans. The pans themselves hold large numbers of a variety of waders (shorebirds) in winter, and small birds such as bluethroats and Sardinian warblers occupy the scrubby areas. The tracks will take you eventually to the railway station at Porta Nova – about 5km by the shortest route, but it can take all day if you meander around the saltpans. The black-shouldered kite (above) was hunting over fields just north of the station.
Easy access along roads/tracks by the saltmarsh and saltpans along the coast to the west. However, I have not explored this area yet.
Olhão is a town without any obvious nature interest, but follow the track 2km east of the station (all along paved roads) and you come to the headquarters of the Ria Formosa Natural Park at Quinta de Marim. An alternative route via back roads and past the harbour is do-able if you have a map of the town.
The quinta is described as a microcosm of the natural park, with pinewoods, saltpans, saltmarsh, grassland, a freshwater pond, and mudflats. In one corner, the animal hospital takes in injured birds for rehabilitation to the wild. A large building houses exhibitions and offices, while an old mill on the tidal embankments provides a reminder of life in the past.
We’ve seen 50-60 species of birds here on each of our visits, and in February-March a variety of plants and butterflies too. If you are very lucky (and we haven’t been, so far) you may see a chameleon hidden on a pine tree.
The broadest part of the Ria Formosa Natural Park is adjacent to Faro. You can overlook it from Faro Station, or follow paths either way along the shore. If the tide is out, birds can be difficult to see in the channels. The best time is when the tide is rising and pushing birds closer to the shore. Or as it falls and the birds move from their roosting places back out onto the mudflats.
In January 2019, we watched a flock of about 350 cormorants moving out to feed. Those at the front of the flock landed on the water and dived, the next few landed ahead of these and dived, the pattern continuing as the first cormorants surfaced, took off, joined the crowd and flew to the front to repeat the process.
The stations between Faro and Portimao are further inland, and while there is probably some birding interest around them, they are not prime watching sites.
The railway line runs past saltpans and saltmarsh near Portimao and Ferragudo, but I don’t know how accessible any of it is on foot/bicycle without being on very busy and fast roads.
Mexilhoeira Grande Station
Probably my favourite walk in the Algarve is around the Quinta da Rocha peninsula in the Alvor estuary. From the station, you just follow the tracks westwards, alongside the western marshes, down to the saltpans, and up through the farmland, past the A Rocha environmental education centre at Cruzinha, and back to the station. You can expect to see 50-60 species of birds during a day here, with a few plants, butterflies and other critters even in January. Ospreys, Caspian Terns, Spoonbills, Zitting cisticolas (above), stonechats – just to give an idea of the range of species (and sizes).
Upstream of the station you come to tidal marshes and old saltpans occupied by stilts and storks and other wildlife. Once you get away from the busy main road, it is quite pleasant. We spent some time in a small marshy area known as Paul de Lagos, listening to Cetti’s warblers, reed warblers, corn buntings, and watching marsh harriers, among many others.
Downstream, the road goes past the marina, and along the canalised river. Terns and cormorants are most common here, but in stormy weather there can be other seabirds. Continue along the road and through the town for about 4km to Ponta da Piedade for more birds and some spectacular coastal scenery.
Another route takes you along the beach (or through the valley behind the hotels) eastwards to Meia Praia station – and beyond that to a shallow lagoon just west of the Alvor Estuary, where we came across over a hundred Mediterranean Gulls feeding. Iberian magpies (below) are abundant in this general area.
Lagos is the last station on the line, but a short walk into town will take you to the bus station where you can continue to Sagres and Cape St Vincent – the most south-westerly points of mainland Europe.
Over the last few years, local birdwatcher Goncalo Elias produced am excellent series of birding hotspot books, each covering a particular area of the Algarve. You can still buy these individual volumes, but they have now been combined into a single book.
Each chapter begins with a two-page introduction, which highlights some interesting birds that can be seen in each area and how the hotspots look like. After that, detailed information is provided for each hotspot: a brief description, a list of the most interesting birds that can be found there, and some suggestions on how it can be explored.
The original series certainly allowed us to find more sites and birds in each area than we had previously been aware of.
If there was a book like this for every area I visited, I’d be a very happy camper. It takes you through the year in fortnightly chunks, with information about plants, birds, invertebrates, places, etc, etc.
It is a general guide to the most obvious bits of natural history, so if you are a specialist in birds, or botany, or butterflies, you’ll need a specialist book for that, and this will help with everything else.
P.S. Buying books through these links brings me a small commission (at no extra cost to you) which helps with the costs of maintaining this website.
