Again and again we are asked to give talking points for a class trip to Barcelona. Here we have an - incomplete - list of arguments as to why it is worth arranging a class trip to Barcelona or other trips in the group. The arguments, of course, apply for all travellers, whether single or in a group of 20 persons.
Barcelona is prepared for the needs of group travellers in particular:
Barcelona has got countless museums, some of which enjoy world fame and do not take second place to famous museums such as the Prado in Madrid, the Louvre in Paris, the Met in New York. The best-known museums and those worth seeing are being introduced on the page “Museums”.
The museums in Barcelona represent a wide range of subjects: art, history, zoology, archaeology, engineering, architecture and much more.
The city is dedicated to famous personalities like Picasso, Miró or Gaudí. Large Museums, parks and buildings are devoted to them and bear their distinct signature.
In addition to the museums and monuments, Barcelona also offers a wide musical range. Many festivities, festivals and concerts can be visited.
Despite its 1.6 million inhabitants, Barcelona has kept much of the original life. In every district, to the present day, you will find a market where groceries are being brought on a daily bases. Southern serenity in the parks with a game of bowls, but also the opposed hectic atmosphere on the streets can be observed. At night, you can go out and celebrate for as long as you wish to.
Until today you can experience in the Catalan capital, how the trauma of decades of oppression of one's own culture has been processed and still is. The emphasis on their own language in public and the many typical Catalan festivals are the only obvious signs of this. This gives Barcelona a unique flair, which as well is not hidden to the tourists.
The people in Barcelona are friendly and supportive, even if you do not speak Catalan. A Catalan "bon dia" instead of the castellan "buonos días" already breaks the ice and you will be helped in Spanish or any other language.

Barcelona is best prepared for group travelers.
