Barcelone's identity is inseparable from the work of Antoni Gaudí, whose seven UNESCO-listed buildings define the city's skyline. The must-see include La Sagrada Familia, Park Güell, Casa Batlló & Casa Milà, the Gothic Quarter and El Born neighborhood.

Three days covers the main Gaudí buildings, the Gothic Quarter, El Born, and the waterfront at a comfortable pace. A fourth day is the sweet spot allowing to visit the city’s highlights and hidden gems.

Book iconic Barcelona monuments like the Sagrada Família one to two months in advance, and other major sites at least two weeks ahead, to guarantee your spot.

The metro is the fastest and most practical way to travel, using contactless or reloadable cards for a few trips, the Hola BCN! card for unlimited travel including airport transfers, and the T-Casual (€12.55 for 10 trips) as an alternative for central hotels. Barcelona is also incredibly walkable, so you should avoid rental cars because the city center is a restricted zone for non-residents and parking is difficult.

To comply with tightened local regulations, do not drink in non-designated areas or wear swimwear away from the beach to avoid penalties, and keep your shoulders and knees covered while maintaining silence in churches like the Sagrada Família. Additionally, remember this is a proud Catalan city, so menus, signage, and daily interactions occur primarily in Catalan.
