Budget route
The cheapest way to the towers
The official sagradafamilia.org website sells a basilica + towers ticket for €36 per adult (€26 basilica + €10 tower add-on, 2026 pricing). You choose Nativity or Passion at booking, pick your entry and tower time slots, and explore at your own pace with the included audio guide app. This is the only confirmed route to the Nativity facade if the bridge walk and Gaudí-era carvings are your priority.
On GetYourGuide, the equivalent self-guided entry ticket with audio guide starts from around $39 and has over 108,000 reviews at 4.64 stars — by far the most-reviewed Sagrada Familia product. It offers the same tower access with the flexibility of GetYourGuide's cancellation terms.
The trade-off: no live guide means no real-time interpretation of the symbolism or construction story. Most of what a guide covers is in the official audio app, but it takes more self-direction. For architecture enthusiasts who read up beforehand, that is rarely a problem.
