In my opinion metro in Barcelonais the most convenient way to travel. Barcelona has the most convenient, clean and simple metro I’ve ever seen in European cities. But if you don’t like travelling by metro or if you are going to spend very little time in Barcelona you can use a tourist bus (Barcelona Bus Touristic) as one of the most interesting and comfortable ways of travelling.
There are two tourist bus tours inBarcelonasuch as Northern one or Route red with red-colored buses and bus stops, and Southern one or Route blue with blue-colored buses and bus stops. During your travel you can listen to a guide in any language including English. As for running times Barcelona Bus Touristic offers daily service with buses going every 20-30 minutes and making around 30 stops at the city’s most attractive sites. The fare is around 20 euro per 2 days. This sum of money will allow you to see everything with no extra vehicle expenses. Tickets may be purchased at railway stations and hotels as well as at central bus stops like e.g. at the Catalonia Square (Plaça de Catalunya).
