December in Lisbon brings festive lights along Avenida da Liberdade, holiday markets in Rossio and Eduardo VII Park, and seasonal live music and Fado performances across Alfama and Bairro Alto. Key experiences for December travelers include the Christmas markets (Mercados de Natal) offering local crafts and gastronomy, the illuminated streets and window displays in Baixa, and New Year’s Eve celebrations with fireworks at Praça do Comércio. Nearby cities like Sintra and Cascais are popular day trips for winter vistas and quieter cultural sites; Porto offers a cool, atmospheric alternative with its own holiday markets and port wine tastings. Booking concerts, popular restaurants, and guided excursions in advance is recommended during December weekends.
