Barcelona travel tips
You better not rely on Uber in Barcelona
Uber has met strong resistance in Barcelona from both local authorities and taxi drivers. Despite the company’s efforts, its status remains dubious. Note that taxis are quite expensive in Barcelona. For instance, a 10-kilometre ride will cost around €14. However, the public transportation system is well-developed, so you may not need to use a taxi at all.
When in Barcelona, go to CosmoCaixa — one of the most renowned science museums
CosmoCaixa explains science via vivid experiments. After entering, visitors descend 30 meters below in a gigantic spiral winding around a giant tropical tree. The rotation of the Earth is demonstrated with the help of a 40-metre long Foucault pendulum. In a geological section, you can see how the shape of a volcano develops. The nature of sound is shown with the help of two satellite dishes 80 metres apart, transmitting sounds between them. No boring formulas, try and see everything yourself!
Bus tours are not the best way to explore Barcelona
Barcelona offers so many interesting places to see that you may be at a loss where to start. At first sight, the sightseeing bus seems like a good idea. However, you might have to wait in queues and move around in a packed vehicle. Besides, a bus can’t squeeze into tiny streets of the historic areas of the city. On the other hand, using comfortable city transport and walking will prove to be much more rewarding. Don’t rush through Barcelona; take your time to savour it!
