This trail offers one of the best ways to enjoy the serene lagoons and salt marshes of Ria Formosa, a natural jewel and one of the most important wetlands in the Iberian Peninsula. Protected from the open sea waters by a wide stretch of sandy islands, the lagoons provide shelter for a variety of waders and long-legged birds, as well as to shellfish and notable fish species, including two endangered species of seahorses.

At the start of the trail you will notice the vast sand dunes that stabilize the barrier islands facing the ocean*. These dunes also provide a valuable habitat to a wide variety of psammophyte (‘sand loving’) plants, some of them endemic to southern Portugal; notable among these plants are the Portuguese Thyme, a fragrant and very endangered species (discover more here), and the rare and beautiful Spiny Thrift (Armeria pungens). From Quinta do Lago, the only way to reach Gigi Beach and the dunes on the other side of the main water channel is to cross the wooden bridge further down the trail. Besides providing enjoyable panoramas, this bridge – which is the longest wooden bridge in Europe – provides a good opportunity to appreciate the dynamic nature of Ria Formosa and the dune’s rich plant cover. *When the access is made through the main parking site.

Here, low tide brings with it the shellfish catchers that painstakingly collect Grooved Carpet Shell, a gastronomic delicacy that has been harvested throughout Ria Formosa since time immemorial. Following the main trail, you´ll then enter a sparse pinewood where it is possible to observe birds like the Iberian Azure-winged Magpie (Cyanopica cooki), and the bright yellow Black-headed Weaver (Ploceus melanocephalus), a species accidentally introduced from the African savannas. Under the Umbrella Pines (Pinus pinea), maybe you can even detect the protected Chameleons (Chamaeleo chamaeleon) that inhabit these pinewoods.

A bird hide will provide unobstructed panoramas of the lake, a place which is also inhabited by terrapins native to Portugal. Surrounding the lake, in the distance you’ll also see the famous “luxury Algarve villas” of the exquisitely landscaped Quinta do Lago, one of the top luxury destinations in Europe. Further afield, in the shadows of a large carob tree, there is a small tank complex built by the Romans around the 2nd century AD in order to produce a special condiment (called ‘garum‘), very popular at the time, which was prepared from the fermented intestines of fish. After wondering if there was a strong correlation between the ultimate demise of the Roman Empire and the culinary taste of its citizens, you can either make the pleasant way back, or converge with the Ludo Trail to observe flamingos strolling quietly in the saltpans.

Further Tips
If you are arriving by car there are a couple of options to consider. Parking lot #2 (please check trail map above) offers free parking; however, during summer it may be more difficult to uncover available space. On the other hand, parking lot #1 charges a small fee between May and October but it provides better chances to park your car in summer. Both parks are available year-round. The trail may sometimes be waterlogged due to tidal fluctuations along the edge of the golf course. However, that is highly unusual and should not be a problem. Please check the interactive map above for directions. This trail aggregates two well known trails: São Lourenço proper and Quinta do Lago trail.You can also explore this extensive area by choosing one or more of the recommended activities listed below.

Planning a Visit to Quinta do Lago?
You then may want to enjoy the really outstanding beaches located nearby. Stretching west from Quinta do Lago, there is a very long expanse of pristine dunes, soft sand and clear waters. Besides Quinta do Lago Beach, you’ll find the Ancão, Garrão and Dunas Douradas beaches (the latter literally meaning “Golden Dunes”), that have all been awarded the Blue Flag for their high standards. In Dunas Douradas (pictured on the right) and Garrão (near Vale do Lobo), there are two small freshwater lagoons – see Birding Hotspots – where it is possible to find birds like the Little Bittern and the Eurasian Wryneck (Jynx torquilla). If you are arriving from Quinta do Lago and you do not want to walk all 4.0 miles – out and back – it takes to get there, your best option is to use bicycles. However, it is also possible to reach them by car from Almancil. Both free and paid car parks are widely available. There are also some restaurants along the seashore, starting with Gigi’s at Quinta do Lago Beach. Despite being pricey, those are good seafood eateries. Normally, all the fish is freshly caught that same day.
