What to do in Barcelona? [closed]

I'm not a city person, but I've been to Barcelona as a 13-year old in 1998. One day that I particularly remember is when we hiked up Montserrat, very close to Barcelona and interesting both from a cultural and natural point of view. Should probably still be fine even if it's almost November (the picture below was apparently taken in January).

You have to see Sagrada Familia of course. Do the climb up to the top of the tower. See the museumy thing in the basement. Visit the little school right next door with the wavy roof.

In addition to any Olympic-y or other Gaudi things, you should walk down Las Ramblas about 10 or 11pm. Don't have a lot of money on you when you do, so you can relax and gawk at all there is to gawk at.

Eat tapas. Drink beer or cava or both. Eat more tapas. Repeat as necessary.

I also enjoyed Montjuic, the funicular up to it, and the cable car.

Barcelona is well known of their football club. One of the best player in the world (Lionel Messi) is a Barcelona player.

Since you like architecture, you may want to visit Barcelona stadium ( Camp Nou ).The Camp Nou Tour is only open on the non-match day.

Two things that stood out from my last visit to Barcelona in March 2011:

• Joining a laser cutting workshop at the DHUB FAB. This workshop was open to everyone and cost somewhere between 30 and 50 EUR per person for two days. There is also the Fab Lab Barcelona, which is somehow connected.

• Walking up the mountain to the fortress at Montjuïc. The view reminded me of an advertisement for a logistics company: ground vehicles, ships, and airplanes (BCN). Watching the Port of Barcelona from above was fun.
