Costa da Caparica
Costa de Caparica is in Lisbon Region.
Costa de Caparica is located near the Tagus river's mouth, near Almada, just 10km south of Lisbon. It is well known for its extensive beach - the largest contiguous beach in Portugal, spanning approximately 30 kilometres.
Part of the municipality of Almada, Costa da Caparica is a typical Portuguese beach town. It is surrounded by the Arriba Fóssil, a magnificent set of rock cliffs and is easily accessible from both Lisbon and Almada.
The town center is not very interesting, but provides some great seafood restaurants and shopping.
But the real gems are to be found on one of the 20+ beaches in the Area - most of them have bars and surf schools that are open all year round.
As with the rest of Portugal, Portuguese is the main language in Lisbon. However, most younger people know enough English for basic communication, and it is possible to get by speaking only English. Spanish is widely understood, though few are fluent in it, and many locals will respond more readily to English than to Spanish. Nevertheless, any attempt to speak Portuguese is always appreciated, and even simple things like basic greetings will often draw smiles and encouragement from locals.
