The very first step: book your time-specific ticket online in advance. Tickets on the door are more expensive (often about €4 more) and the risk of “sold-out time slots” is real—especially during the busy April-September season and weekends. Also note that for any special experience tickets, such as concert and night visits, booking a ticket online will be required.

Ticket levels vary: there’s the standard entry with an audio guide and Gaudí Cube experience, and higher-tier tickets (Silver, Gold, Platinum) that include early-access, access to the Gaudí Dome, VR tablets, rooftop concert or cava, flexible cancellation and fast-track entry. Children under 12 may be free with some offers, and discounts apply for students, over-65s and local residents.

To avoid the thickest crowds, aim for early morning slots (around opening at 09:00) or later afternoon/early evening visits. Weekdays (Mon–Thu) outside high-season are noticeably calmer. Arriving just a few minutes after opening or choosing an early slot can make a big difference in your experience.

Once inside, spend time on the rooftop terrace with its dragon-scale chimneys and panoramic city views before the general flow of visitors arrives. From there you can descend into the attic, the noble floor, and finish with the basement Gaudí Cube experience. Wear comfortable shoes—some staircases are steep and narrow, and though lifts exist, the experience is richer if you take the stairs at least partway.

Accessibility is easy: Casa Batlló is equipped with lifts and wheelchair-accessible routes, though some upper roof terraces may still have limitations so visitors with mobility concerns should check ahead. The building is especially family-friendly with interactive audio guides in multiple languages. Insider tip: the “Night Visit” or “Magical Nights” sessions (which include live music, cava on the rooftop and lower visitor density) offer a more relaxed experience—if your schedule allows it and you don’t mind paying a premium.

Finally, while you’re there, glance at the façade from across the street—the tram and tree lines open up in the early morning or winter months a perfect unobstructed view. Bring a camera, arrive early, and let yourself soak in the curves, color and imagination of Gaudí up close.
