Visit Barcelona it is wonderful, whether you are going there for the first time or the second or the third, in my opinion it will always be magnificent and unique. A way to visit it spending little is to choose free attractions, maybe not all of them also because they are essentially 13 the most important ones, but at least you will be able to combine the beautiful city with a low budget.
CaixaForum cultural center where you can attend conferences, shows and multimedia events, always free. Attention, the Caixa Forum is no longer free from May 2013.
Estadi Olimpic for football lovers it is an impregnable stop, pay attention because the Olympic Gallery is subject to charges.
Jardins del Laberint d'Horta a well-kept and beautiful park in the heart of Barcelona, inside there is also a labyrinth. On Wednesdays and Sundays, admission is free.
Chocolate Museum chocolate gourmets cannot fail to go, scale models of monuments and famous people. The first Monday of the month is free.
Picasso Museum a little gem for those who love art and Picasso, the first Sunday of the month is free.
Park Guell a classic, one of the most beautiful and perhaps discounted places in Barcelona, but it is good to reiterate it ... it's free, always!
