The São Pedro de Alcântara lookout may not be Lisbon’s highest viewpoint—that honor goes to the Nossa Senhora do Monte lookout—but it’s certainly its most romantic, offering panoramas of the city’s signature fortress, Castelo de São Jorge, perched ominously on the opposite hillside. In addition to the vista itself, the area offers pleasant gardens, which are perfect for lazing about, and a kiosk that regularly hosts jazz and other live entertainment. Come here at sunset and enjoy a sundowner as the city lights up below, then head to nearby neighborhoods Bairro Alto or Príncipe Real for a night on the town.
