Plan the day: Allow 1.5–2 hours for Sagrada Familia, 1–1.5 hours for Casa Batlló, and about 30 minutes to transfer and reset. A comfortable combo takes 4–5 hours.

Choose your format: Pair Sagrada Familia fast-track tickets with a later Casa Batlló slot, go guided with Sagrada Familia fast-track guided tour, or use the Headout Barcelona Pass for more flexibility.

Know the highlights: Sagrada Familia covers the stained-glass nave, museum, and optional towers; Casa Batlló brings the bone-like façade, flowing stairwell, lightwell, attic arches, and rooftop chimneys.

Sagrada Familia: Usually opens at 9am, with seasonal closing between 6pm and 8pm; Sunday and holiday entry often starts later. Timed entry is strict, with only a short late-arrival buffer.

Casa Batlló: Open daily 9am–10pm, with last entry around 9pm. Evening slots feel moodier, but midday usually gives you the clearest rooftop and façade photos.

Start at Sagrada Familia: Its entry window is tighter, security takes time, and early slots are calmer. Reverse the order only if you’ve booked Sagrada for late-afternoon stained glass.

Best timing strategy: Pair a morning basilica visit with an after-lunch Casa Batlló slot for lighter crowds, or do Casa first and aim for 3pm–5pm inside Sagrada for warmer light.

Sagrada Familia: The basilica is wheelchair accessible, though tower access is not. Guide dogs are allowed.

Casa Batlló: Most routes are manageable with elevator support, but the historic layout can feel tighter than the basilica’s open nave.

Sensory planning: First-entry slots are the calmest at both sites; Sagrada’s central nave also has benches if you need a seated pause.

Service animals: Assistance dogs are generally accepted at major Barcelona landmarks, but carry documentation.

Lock Sagrada first: Its timed entry is the less forgiving one; build Casa Batlló around that slot.

Use the walk wisely: The 25-minute route works well as a coffee break between two visually dense interiors.

Add a quick extra nearby: Recinte Modernista de Sant Pau pairs well with Sagrada, while Casa Amatller sits right beside Casa Batlló.

Chase the light: Morning flatters the Nativity Facade; late afternoon gives Sagrada’s western windows their richest color.

Save rooftop photos for later: Casa Batlló’s roof and façade read best once the hard midday glare softens.

Dress for a church first: Covered shoulders and knees matter at Sagrada, even if Casa Batlló has no comparable dress code.

Keep bags light: Fast-track Sagrada tickets still include security screening, so bulky bags slow the start of your combo day.

Download audio content early: If your Sagrada ticket includes an audio guide, sort your phone, battery, and earphones before leaving.
