Arrive at Gaudi's Casa Batlló in Barcelona with your priority access voucher, also available on your mobile device for extra convenience, and skip the often-long lines to head directly inside. Pick up your included audio guide and map, which will walk you through this spectacular example of Gaudi's architectural style.
The audio guide will take you through the museum's 5 distinct areas, such as the Noble floor, where the Batlló family once lived. Head up to the loft, which acted as a laundry room and cupboard, from which you can access the roof terrace. You'll see the unusual chimneys and 'Dragon Black' a model that depicts the dragon slain by St. George. As you wander around, notice the artist and architect's meticulous attention to detail in the door handles, skylights, and banisters.
End up in the home's entrance hall, dominated by a dramatic staircase made to look like the spine of a huge animal. After your guided audio tour is finished, you are free to stay as long as you like.
