Barcelona's two terminals sit four kilometres apart and the train only serves one of them, which is why the best route in is different depending on where you land. What each option costs in time, the ticket that works on the train but not the metro, and the metro that does not reach the centre.
Barcelona's tap water is treated to European standards and safe to drink, but a lot of locals buy bottled anyway, which visitors reasonably read as a warning. Why the water tastes the way it does, how to ask for it in restaurants, and what the habit actually costs you.
Barcelona is larger than visitors expect and the Gaudi sites are scattered across it, which is why four days works where three feels brisk. How the days divide by district, what the doubled 2026 tourist tax now costs per night, and why booking slots should come before booking flights.
Barcelona is safe in the way that matters most, since violent crime against visitors is rare. What it has instead is one of Europe's highest pickpocketing rates, concentrated in a small number of predictable places. Which areas need care, which do not, and the habits that remove most of the risk.
