Activities in Lisbon

Tram 28 is Lisbon's most famous public transport line — a vintage yellow remodelado streetcar that rattles through the city's narrowest streets, connecting Martim Moniz to Campo de Ourique via Alfama, Graça, Chiado, and Estrela.

The Lisbon Oceanarium at Parque das Nações is Europe's largest indoor aquarium, designed by Peter Chermayeff. Its centrepiece is a colossal 5-million-litre open-ocean tank visible from every floor, surrounded by four habitat galleries.

Sintra is a UNESCO Cultural Landscape of Romantic palaces, misty forests, and Moorish castle ruins set in the hills 30 km northwest of Lisbon. Easily reached by a 40-minute train from Rossio station, it's Lisbon's most popular day-trip destination.
