cosmocaixa

cosmocaixa is a science museum set up above the city beyond the top of avenida tibidabo. you will need to take the metro, then walk the rest of the way up the steep street, or you can take the tramvia blau most of the way. I recommend the bus and the walk, as avenida tibidabo is very different from the barcelona you will come to have known. Once inside, expect skeletons, mechanical demonstrations of natural processes, living creatures, and the world's only indoor mangrove forest, complete with flora, fauna, and frequent rainstorms. The outdoor area affords great views of the city, and admission is only 2 euros for students with id (3 for adults). It's open tuesday-sunday, 10-8 and worth a look to experience something different.
