The interior of the CosmoCaixa museum in Barcelona, Spain.

One of the city’s most popular family-friendly attractions, this science museum covers many fascinating areas of science, from fossils to physics to outer space. The highlight is the re-creation of more than 1 sq km of flooded Amazon rainforest (Bosc Inundat); over 100 species of Amazon flora and fauna (including anacondas, poisonous frogs and capybaras) live in this unique, living diorama in which you can even experience a tropical downpour.

In another original section, the Mur Geològic, seven great chunks of rock (90 metric tons in all) have been assembled to create a 24m-long wall showing different geological processes. Outside, you can stroll through the extensive Plaça de la Ciència, whose modest garden flourishes with Mediterranean flora.
