Continuous Metro service on Saturdays
Since April, 2007 you can enjoy Saturday´s nightlife without having pressure to miss the last Metro to get to your accommodation in Barcelona.
Opening hours have been changed as well for Fridays (5:00 a.m.-2:00 a.m.). From Sunday till Thursday the Metro operates from 5:00 a.m. to Midnight.
One of the recent highlights is that you can find Metro timetables on Google Maps.
Travelling by Metro is cheap and it comprehensively covers most of the city. Tickets can be bought in every station by a ticket machine.
If you are coming for a short-term-stay to Barcelona, the most recommendable ticket is the T-10 (10 passes for 6,90 ?). There are also day cards available but they are only worth it if you want to travel a lot.
