As posted in previous thread;
On the pickpockets front, make sure you avoid the groups of girls who tend to be nearer the bottom end of Las Ramblas during the evening. If you’re a target they’ll be all over you in a harassing sort of way and if you don’t have your wits about you wallet, watch, phone etc will be gone. Don’t think the whole place is like this, just be aware as last time I was there, (albeit on a stag do so lets just say some were none too complicit) a few of my friends were robbed.
To add one girl was just pulling one of my mates by the arm and had his watch off in the process. I just walked round with my hands in pockets and barged my way through.
