1. Not Purchasing Tickets in Advance

By far, the biggest mistake you can make is not buying your tickets ahead of time.

La Sagrada Familia is one of the biggest attractions in Spain, drawing in millions of visitors each year.

Tickets almost always sell out and must be purchased on the official website as early as possible. Tickets are usually released 1-2 months in advance.

You can’t simply show up and buy your tickets on the spot!

Tip: If tickets are sold out on the official website, check Viator or GetYourGuide for tours that may have last-minute availability.

2. Only Seeing the Exterior

While the exterior of La Sagrada Familia is impressive, I’d highly recommend buying a ticket to go inside rather than just admiring it from the street.

The interior is even more incredible, with towering columns and colorful stained glass windows that fill the space with natural light.

Plus, you’ll get a much closer look at the Nativity and Passion facades, where you can appreciate all the intricate details and symbolism.

Since the exterior is usually surrounded by construction barriers, you really can’t get the full experience without going inside.

3. Not Booking on the Official Website

There are numerous third-party websites selling tickets to La Sagrada Familia, but not all of them are reputable.

Some of them look very similar but charge much higher prices for the same tickets.

For example, look-a-like websites like www.sagradafamiliatickets.org, are selling tickets for more than double the price!

To ensure you are getting the best deal and avoiding any potential scams, always book directly from the official website (https://sagradafamilia.org/en/tickets).

4. Not Dressing Appropriately

La Sagrada Familia is a place of worship, so there’s a dress code you’ll need to follow to be allowed inside.

Make sure to dress appropriately by covering your shoulders and knees, avoiding see-through clothing, and removing any hats before entering.

If you’re visiting Barcelona in the summer, I’d recommend bringing a light scarf or shawl to cover your shoulders if you’re wearing a tank top or sleeveless dress.

The dress code isn’t overly strict, but you don’t want to risk being turned away at the entrance.

5. Not Bringing Headphones for the Audio Guide

If you opt for the basic entrance ticket, an audio-guided tour is included.

However, how it works is that you must download the Sagrada Familia app on your phone, and play the audio guide through the app.

Headphones are not included, so you’ll want to be sure to bring your own headphones to get the best experience.

Otherwise, you’ll have to hold your phone up to your ear the entire time, which can make it difficult to hear in a loud and busy place.

6. Skipping the Towers

La Sagrada Familia has two towers you can visit (the Nativity Tower and the Passion Tower), which offer incredible views of Barcelona and a closer look at GaudĂ­’s architecture.

While tower access costs extra, I’d recommend adding it to your ticket if you want the full experience.

You’ll take an elevator up to the top, where you can enjoy the views, and then walk back down a very narrow spiral staircase.

7. Visiting at the Wrong Time of Day

La Sagrada Familia is one of the most famous churches in Barcelona and is almost always busy.

But there are some times of day that are better to visit due to the natural light shining through the stained glass windows.

I’d recommend trying to visit from 4-5PM when the sun casts a soft light inside.

You’ll also be able to get some good pictures of the interior columns lit up in colors.

8. Not Downloading the App Ahead of Time

The official Sagrada Familia app is required for the audio guide, as well as to download your entry tickets.

Make sure to download the app and add your tickets before arriving at the site.

This will help you avoid any potential issues with wifi or mobile data connections at the entrance.

9. Not Arriving Early Enough

Another common mistake tourists make when visiting La Sagrada Familia is not arriving early enough of their scheduled entry time.

Once you arrive, you have to go through security and metal detectors, which can take some time depending on the crowds.

To avoid any delays or risking missing your scheduled entry time, aim to arrive at least 15-20 minutes before your ticketed entry.

This will also give you time to meet your assigned tour guide if you’ve opted for the guided tour.
