Doing Castells, which means Castle in English, is more than building human towers.
Colles Castellers or teams, organize some activities to make closer the relationship of the members from la Colla.
One example of this is the Torneig de Futbol, which is an activity where all Colles are invited to play football together.
This year, it's celebrated on the 26th and the 27th February in Granollers, and it has a maximum of 32 teams, one per Colla.
Each member who will attend, has to pay 20€ and it will cover the dinner, the concert on Saturdays night, the place to sleep, the breakfast and the lunch of Sunday and it's included too a little present for each member.
As you can see, being in a Colla is having friends, and being in a little family, being confidence with them and respecting. I thing it's a good way to learn how to act in some diferent situations.
The members of the Colla do more activities like, going to Port aventura and going skying together.
