Seixal has a bay that comes from the Tagus River (Rio Tejo). In the last few years, the condition of the sidewalk was greatly improved and now you can take a good and relaxing stroll all around the bay.
In the summer there are free activities nearly everyday.
Seixal used to be home to Portugal's longstanding maritime tradition that included naval construction and repair of wooden boats, painting and decorative arts, sailmaking. Situated on the edge of an entry to an inlet, it was the perfect place for these activities, as the waters around were calmer and there was better protection from the strong winds that usually buffetted the more exposed areas of the delta.
For a long time, since the middle ages, numerous boatmakers dotted Seixal, constructing boats for fishing, passenger, and cargo traffic. Since the construction of the 25 de Abril bridge which connected Lisbon to the other side of the Tagus int he 1960s, the boat industry has since disappeared. The municipality of Seixal, however, has tried to revive these traditions by reconstructing some traditional boats at least a century old and converting them to tour boats. Tours are offered from spring to autumn.
A small boatmaking center is located right at the quay, which gives a good idea of the maritime traditions of Tagus. It showcases an impressive collection of models of all the types of wooden boats constructed here in Seixal. There is also a work area where classes for model boatmaking is undertaken for young people.
The oldest part of Seixal is located where the tourism office is located, a long and narrow area between Avenida Alvares Pereira and Rua dos Reis. Narrow streets and old houses will be a great reminder of Lisbon's Alfama district for those who have already been there, but without any hilly areas. There are houses with nice azulejo panels, as well as some street names associated with the regional history, like Rua dos Pescadores (Fishermen Road). There are nice squares in various points whose main one is dominated by an old church, as well as a small park on Avenida.
Fogueteiro is probably one of the top 3 busiest stations on the Fertagus line outside Lisbon. Privately operated, this train between Roma-Areeiro and Setúbal is the most convinient way to get to the suburban areas of the Outra Banda, as well as Costa da Caparica in Almada. For more information about Fertagus itself, please check out the tip on my Setúbal page.
From the Fogueteiro station, a few different buses operated by Sulfertagus and TST go into the center of Seixal, as well as other areas in the region like Amora, Lisbon, and as far as Setúbal. The bus stops are located right outside the main entrance of the station, and most routes, especially the Sulfertagus services, are operated according to the train times. Tickets need to be purchased on board.
Fogueteiro is the station serving Seixal, and is also one of the busiest stations on the Fertagus line. Previously being the southern terminus of the route coming from Roma-Areeiro in Lisbon, the station gets quite crowded during rush hours. The services to both Coina and Setúbal stop at this station, and they are well-connected by buses to Seixal and other surrounding areas.
Although it belongs to the Sesimbra area, Praia do Meco is easily reached from Seixal by car. A wide, clean beach in a protected area, Meco is a very popular spot for those want to enjoy the beach and the view at the same time, as well as a rather "adventurous" journey on the road. There is a small tourism post on the beach, in addition to two cafes/restaurants that welcome visitors all the time. The fishing boats on sanddunes remind people of the history of the region as an important fishing center - which Sesimbra still is at least.
