Visit La Sagrada Familia in Barcelona on a 1.5-hour skip-the-line tour! With a knowledgeable local guide, head straight past the cathedral's long entrance lines to learn all about the UNESCO-listed cathedral and its charismatic creator: Antoni Gaudi. After exploring the monument, visit the onsite La Sagrada Familia Museum to see an array of cathedral artifacts. If you have more time free, and want to admire bird's-eye views over Barcelona, upgrade to include a skip-the-line entrance ticket to one of the cathedral's magnificent towers.
