Rain flatters Barcelona more than you would think — the crowds thin, the stone darkens, and the city’s greatest interiors get their due. Here is a full day plotted entirely under cover, moving by metro and short dashes.
Key facts
- Book ahead: the Sagrada Família and Palau de la Música both sell timed tickets that vanish on wet days
- Transfers: everything below sits on or near the metro; no walk exceeds ten minutes
- Rain bonus: stained glass is actually better under bright overcast — diffuse light, no glare
9:00 — The Sagrada Família, inside
Start at Gaudí’s basilica with the first slots of the day. The interior is the point in this weather: a forest of branching columns under glass that pours colored light down the nave. Ninety minutes with the audio guide is about right.
