Local trains can take you to the outer edges of the city and to the beaches. Avoid travelling during rush hour, as public transport can get very crowded. Look for discount or multiple-trip tickets such as the Passe Turistico, bulhete diario (day pass) and the rechargeable Andante Card to save money.
