Trains traveling to the southern part of Portugal depart from several railway stations in Lisbon, including Sete Rios, Oriente, and Entrecampos train hubs, so it's advisable to double-check your departure point when booking your ticket. It is also essential to know that some rail services available on the Lisbon - Albufeira line aren't direct, and you will have to change trains in Tunes. Despite the chosen type of train, your final stop is Ferreiras station which is well-connected to Albufeira public transport network, thus you can start your exploration immediately upon arrival.
