Even though Portugal is predominately Catholic, the Portuguese are pretty tolerant of non-traditional lifestyles. Porto has a reputation for being on the conservative side, but gay rights are slowly gaining a foothold.
Gay pride takes place in July, although the festivities are fairly new to the city. You won’t find a designated gay district, but clubs like Boys R Us (Rua Dr. Barbosa de Castro 63), Café Lusitano (Rua José Falcão 137), Labirinto (Rua Nossa Senhora de Fátima 334) and Moinho de Vento (Rua de Sá de Noronha 76-78) cater to gay and gay friendly clientele. Porto has made leaps and bounds in recognizing gay and lesbian rights, but Lisbon is considerably more open.
