Barcelona city bus tour is perhaps the best way to see the city, its architecture and districts. Tourist bus transportation is carried out by two competing firms: Barcelona Bus Turistic and Barcelona City-Tour. Having bought 1 or 2-day ticket (23 to 30 euros ), a tourist will have an opportunity to use the bus non-stop from 9 a.m. till 8 p.m. and choose any of the three existing routs which embrace whole Barcelona from Monjuic to the port and from Tibidabo to the Old City.
The bus stops at the most popular and famous sights ( like Sagrada Familia ) where you can leave the bus and then enter it again as many times as you like. The buses move in 5 ľ 10-minute interval. By the way, they usually have English audio guides you can listen to with the help of free earphones which you will get along with the bus pass.
