Barcelona is Gaudí, the sea and tapas in one city. Gaudí's works — the Sagrada Família, Park Güell, Casa Batlló and Casa Milà — are a UNESCO World Heritage Site.
Gaudí
Book the Sagrada Família and Park Güell online in advance — on-the-day tickets often sell out. Casa Batlló and Casa Milà are both on Passeig de Gràcia and easy to combine.
Neighbourhoods
The Gothic Quarter has medieval streets and the cathedral. El Born has bars, boutiques and the Picasso Museum. Gràcia has squares where locals sit late into the night. Barceloneta has the beach and small fish restaurants.
Views
Montjuïc with its gardens and museums, the Bunkers del Carmel at sunset, and Tibidabo with its amusement park and view over the whole city.
Food
La Boqueria for the sight, neighbourhood markets like Santa Caterina for shopping. Tapas, weekend vermouth, cava. Places and events are in Places and Events. Watch your pockets in crowds.
