As nightlife starts late, first enjoy delicious food and wine in one of the traditional restaurants in Bairro Alto. Then move to one of the cafés or bars for a drink and meet new friends. After midnight clubs start to live up and the night crowd find its way to the clubs and bars.
Lisbon has grown famous for its nightlife. It has that well-siesta-ed Mediterranean vibrancy, where things are only just getting started at 2am, and the bars stay open for, well, nigh-on forever.
From their there is a little train (like a theme park train!) which brings you to the beaches. The beaches are numbered 1 20. The gay beach is at number 17/18/19. Not that hard to find, you usually can follow the other gay boys!
Behind the beach is a very large cruising area; usually very crowded from 4pm. Be sure not to miss the last train back!
