With the biplane tourist bus one can run into the most important sights of Barcelona comfortably and timesavingly. An important stop is the "Platz Catalunya", a lively place in which a department store is located. On Sunday the Sardana is also danced here. There is a blue and a red bus line which different sights carry away. TheTicket is valid for the two busses and one can interrupt the journey repeatedly.
A bus runs in summer every 5 minutes so that the waiting time is not too long.
