I will go by car (and my car is full with other CS friends). So, depends if we can get enough cars, we will choose so towns closed to Barcelona (Palamos, Sant Antoni de Calonge). Otherwise, the train just arrive to few towns close to the coast, as Portbou, Colera or Llançà (it takes the train 2 hours and half from barcelona center).
to resume: I will wait until next monday (29 of april) to choose what will do. If someone wants to join, write here and say if he/she has car.
