While the Sagrada Familia looms large over Barcelona—it’s visible from many parts of the city—the cathedral should be seen up close and from within to truly be appreciated. Visitors can tour the interior on their own, on a guided tour, or with an audio guide. It’s also possible to take an elevator up one of the towers for sweeping views over the city.
Just about every sightseeing tour in Barcelona includes a stop here, as do hop-on hop-off bus tours, which also stop at Park Güell, Casa Batlló, La Pedrera, and Plaça de Catalunya. It’s possible to combine a visit to the Sagrada Familia with a half-day trip to the nearby mountain abbey of Montserrat or the medieval city of Girona.
