Montjuïc is a busy gay crusing area both by day and by night. It’s very popular any time of the year, but especially in Summer of course. You can meet a great diversity of gay guys here, from local students, to tourists, or guys doing their jogging. The parc being very big, follow the map to get to the right place, or head Northeast of the Passeig de Jean Forestier. But considering the size of the parc, it’s not the only cruising area. You also have a many gay guys around the Ethnographic and Archaeology Museums. The best solution is probably to take some time to explore the parc itself and find your favorite spot.
Such a cool cruising area! I love it, and try to visit every time i come to Barcelona. Lots of different guys and some really cute ones, well no surprise, you're in Barcelona after all ! They're all here for the same thing so lots of action guaranteed !
