About Barcelona
Barcelona is what happens when a beach town becomes a major city but never loses its laid-back vibe. Gaudí's architecture looks like a fever dream, the tapas crawls in El Born go until 2 AM, and you can actually swim in the Mediterranean before sightseeing. Skip Las Ramblas; that's for cruise ship tourists.

- •Gothic Quarter tapas bars like El Xampanyet
- •Bunkers del Carmel for sunset views over the city
- •Barceloneta beach, but locals prefer Bogatell (less crowded)
