Santo André – Lagoon, Dunes and Atlantic Beach

Santo André combines Atlantic beaches, a lagoon landscape and nature experiences with a remarkable archaeological history. Praia da Costa de Santo André lies next to Lagoa de Santo André in the nature reserve. Its long sandy beach is bordered by both the Atlantic and the calm waters of the lagoon. This gives the destination appeal for a range of travel ideas: days by the water, walks through dune landscapes, wildlife observation in a protected area and discoveries from several historical periods.

Lagoon and Beach as Defining Features of the Landscape

Lagoa de Santo André is considered the largest lagoon on the Alentejo coast and covers approximately 500 hectares. On the lagoon side of Praia da Costa de Santo André, conditions are suitable for windsurfing and canoeing. Those who want to focus their trip on water and landscapes will therefore find two different sides of the same beach area here: the Atlantic and the calmer lagoon waters.

The Santo André and Sancha Lagoons Nature Reserve is located in the Alentejo and extends across coastal areas of the municipalities of Sines and Santiago do Cacém. Praia da Fonte do Cortiço, also known as Areias Brancas, is also located entirely within this nature reserve. Dune and pine landscapes define its surroundings. When choosing a holiday apartment or holiday house, it can be useful to establish your preferred daily rhythm first: water activities, beach landscapes or nature trails lead to different priorities when planning a trip.

Dune Trails with Different Features

The Poço dos Caniços trail runs along a dune ridge parallel to the coast. It also passes wet interdunal depressions connected to the central basin of Lagoa de Santo André. The Poços do Barbarroxa trail follows freshwater interdunal wetlands at the foot of a foredune that reaches approximately 47 metres in height. Both trail descriptions illustrate the different forms of the dune and lagoon landscape.

The Salgueiral da Galiza circular trail is approximately 1.65 kilometres long and takes around 90 minutes. Access from Galiza is restricted. The trail also includes a wooden boardwalk approximately 900 metres long. The Casa do Peixe boardwalk is approximately 170 metres long.

Nature Observation and Traces of the Past

The Centro Nacional de Educação Ambiental e Conservação da Natureza, or CNEACN for short, serves as a reception centre for visitors to the nature reserve. It provides information about the protected area as well as advice on suitable birdwatching locations. The same centre houses a permanent exhibition on local biodiversity. This is a suitable starting point for travellers who want to shape their stay not only around the beach but also around nature-related topics and close observation of the landscape.

Santo André also has a long human history. Neolithic archaeological materials were found at the site in Santo André. Evidence of Bronze Age settlement has been documented at Casas Novas and Cerradinha on the eastern shore of Lagoa de Santo André. Figueirinha is designated as a Roman archaeological site in Santo André. In addition to the anchorage near Casa do Peixe, there is also a traditional, now dilapidated building that formerly served as a fish auction hall.

Local Cuisine and Further Travel Ideas

The cuisine also reflects the connection with the lagoon. In 2025, the Lagoa de Santo André Eel Festival celebrated its tenth anniversary. Nine restaurants in the civil parish of Santo André took part in the gastronomic event and served eel dishes as caldeirada, ensopado, prepared in a cataplana, as escabeche, and fried or grilled. The festival is therefore one of the documented culinary insights into the local tradition, without making any statement about future event programmes.

When looking for a holiday apartment in Santo André, you can therefore decide which experiences should define your holiday. The lagoon and beach favour a water-focused stay, while the dune trails are ideal for a trip combining activity and landscape observation. CNEACN, archaeological sites and the historic fish auction hall complement this focus with natural history and culture. Families with different interests can thus put together a varied itinerary combining beach, trails, exhibitions, local history and regional cuisine.
