How can I be a good tourist in Barcelona?

Respect local customs by greeting people with "Hola" and "Gracias." Basic courtesy in Spanish is appreciated by locals. Dress appropriately, especially when visiting churches or religious sites. Beachwear is suitable for the beach but not for the city or restaurants.

Be mindful of noise levels in public spaces. Barcelona is a lively city, but loud behavior can be disruptive, especially in residential areas. Follow dining customs by eating at local meal times, which are typically later than in other countries. Lunch is usually around 2 PM, and dinner starts around 9 PM.

Use public transport correctly by purchasing tickets in advance and validating them. Be aware of your belongings to avoid pickpocketing. Respect local laws and regulations, such as no smoking in public buildings and restrictions on drinking alcohol in public spaces.
