Make your way to La Sagrada Familia, one of Barcelona's best-known landmarks, to meet your guide and tour group. Get there just before 9am, when the popular site is open to the general public. Avoid long lines and be one of the first groups allowed inside.
Before entry, marvel at the ornate exterior of the UNESCO World Heritage Site, featuring sharp, soaring spires and incredible architectural detail.
Follow your guide inside for a tour of Catalan architect Antoni Gaudí's masterwork. Look up for dizzying views of 230-foot (70-meter) vaults, colorful stained glass windows and soaring ceilings. Walk down the five aisles in the shape of a Latin cross while listening to your guide's commentary about Gaudí's architectural philosophy and inspiration. Learn about the reason for the church's unfinished state; construction begun in 1882 and was only a quarter complete when it halted in 1926.
Opt to upgrade your experience with exclusive, 30-minute access to the Tower on the Passion façade, where you will have a panoramic views of the city from a height of 215 feet (65 meters). Please note that access to the tower requires a climb of roughly 400 steps.
Following your tour, you are free to explore the site further on your own.
