Miradouro de Santa Catarina
Found in boho Santa Catarina, this viewpoint boasts views from the river to the Ponte 25 de Abril and Christo Rei not to mention student buskers, hippies and loved-up couples. If you are coming from Cais do Sodre, take the 19th century Elevador do Bica funicular up the Rua da Bica de Duarte Belo to get to the top. Noobai Cafe is located there where it is lovely to sit back and watch the view, especially at night.
