Hen do destinaion: Lisbon, Portugal. Bairro Alto (the Upper District) is the crowning glory of Lisbon districts. With its network of steep, beautiful streets and alleyways, it’s a fine place to explore on foot. By day, it’s scenic and serene, but after the lights go out, it’s an entirely different story. Loud and boisterous, Bairro Alto is packed with small bars and restaurants; the streets become an open-air party.
