Things To See In Barcelona In One Day (Architecture Lovers)

ByJoenid Corner Posted on Updated on

If you only have a few hours to explore Barcelona and need to plan your upcoming visit to prioritize the things to see in Barcelona in one day, you are in the right spot. This itinerary is especially tailored for anyone who loves architecture and is fascinated by exploring the history behind Barcelona’s most iconic buildings.

We crafted this itinerary, with the order of the things we did during our one day in Barcelona, because we only had one day to explore before embarking on our Virgin Voyages Mediterranean itinerary from Barcelona.

Note: If you want to hear about our sailing experience, we put a guide on what to expect and how to prepare for when visiting Barcelona, Cannes, Ibiza, Ajaccio, and Palma de Mallorca cruise ports on the Virgin Voyages Mediterranean itinerary.

Things To See In Barcelona In One Day

We found that Barcelona is filled with lovely architectural details in every corner, and all structures are well-preserved. It’s a pedestrian-friendly and bicycle-friendly city filled with trees and shade, making it a pleasant place to walk around.

There are several rich historical spots to explore, and the locals we met were very friendly and hospitable, which is why Barcelona is so popular and receives around 32 million visitors yearly.

Why You Should Visit Barcelona?

There are places for every taste and vibe to discover in Barcelona. If you’re more like us, a cultural traveler, and want to learn more about the history of the city and vegan food in Barcelona, you’ll be amazed by the many famous spots you can see, even within just a day.

Stunning Park Güell

What makes Barcelona even more special is that you don’t have to look far to find incredible architecture because it’s truly on every corner. Much of this is thanks to Antoni Gaudí, whose vision transformed the way people saw architecture at the time. His influence is still alive today, with stunning works that remain some of the city’s most iconic landmarks.

Map of Top Places To Visit in Barcelona

Here’s a map with all the places mentioned in this post, which I prepared for you to have handy for your upcoming visit to Barcelona.

1. Visit Park Güell

The park construction began in 1900 as a project by Eusebi Güell, a wealthy businessman, who wanted to create a luxury residential community. He hired Antoni Gaudí to design and oversee the construction of the park.

The plan was to build around 60 luxury houses, but only two were built, and the project failed due to the distance and poor communication. Later, the park was sold to the city, and it became the park we know today.

What To See In Park Güell?

When you visit Park Güell, these are the main highlights we explored during our visit:

  • Nature Square – Since we entered the park from the upper entrance on Carrer del Carmel, the first spot we came across was Nature Square. This is where you’ll find the famous benches covered in colorful tile mosaics, shaped like a long snake body wrapping around the terrace. From here, you also get one of the best views of Barcelona.
  • Washerwoman’s Portico – Walking down from Nature Square, we reached this unique walkway with stone inclined columns. It almost feels like stepping inside a cave with the way the columns are angled.
  • Hypostyle Hall – Next, we explored this impressive hall filled with rows of columns. It was originally designed to be a market for the neighborhood. What stands out most is the ceiling, decorated with cream tones and colorful mosaic medallions.
  • Monumental Staircase – Finally, the most iconic part of Park Güell: the fountains, the famous mosaic lizard, and the two fairytale-like houses (one now serves as the shop, the other as a small museum).

Throughout the park, you’ll also notice plenty of green areas, perfect if you want a peaceful moment to connect with nature in between exploring Gaudí’s stunning creations.

Tip: If you want the best photos without crowds, we recommend doing the opposite order: start your visit with the lizard, then the columns, then the stone arcades, and finish with the snake-like benches at the top.

Directions To Park Güell

The park is located in the Gràcia district, in the upper part of Barcelona. It’s not very close to the historic center.

How Long To Spend in Park Güell?

When we visited in May, we entered the park right when it opened at 9:00 a.m. and spent about 1.5 hours there. For us, this was the perfect amount of time to see the main highlights without feeling rushed.

That said, Park Güell is big enough that you could easily spend several hours if you wanted to wander around, have a picnic, or even just relax with a book in one of the green areas.

If you’re short on time and only have one day in Barcelona, we recommend focusing on the essentials: the famous mosaic lizard, the Hypostyle Hall with its columns, the stone arches, and the colorful mosaic benches.

Best Time To Go to Park Güell?

From my experience, the best time to go is right when the park opens at 9:00 a.m. That’s when I went, and it felt peaceful, with very few crowds, which made it easier to enjoy and take photos.

Another great time is during sunset, especially if you’re visiting in the warmer months. The weather is more comfortable compared to the midday heat, and the crowds tend to thin out as the day winds down. Plus, watching the city views from the Nature Square at golden hour adds a magical touch to the visit.

Tip: Even early in the morning, the park heats up quickly, so bring a hat and a bottle of water to stay cool while you explore it.

Tickets To Park Güell

It used to be free, but since 2013, the city has introduced paid tickets and daily visitor limits to protect the park from over-tourism.

Note: Tickets sell out weeks in advance, so book early. Even with tickets, you’ll still need to line up.

Tips For Visiting Park Güell

  • Don’t try to walk to the park because the hills are very steep, and you’ll get exhausted and lose a lot of time.
  • For photos, go early. Start with the lizard, then the columns, the stone arcades, and last the snake-like benches, where there’s more space to find a quiet spot.
  • There’s not much else around the park since it’s mostly a residential area, so plan this as a single visit.

2. Visit The Sagrada Família

The project started in 1882, and in 1883, a very young Antoni Gaudí took over. Gaudí completely changed the design, moving away from a typical Gothic cathedral to something organic, inspired by curves, colors, and nature. Gaudí dedicated most of his life to this project.

He built a physical model, where strings with weights were hung from the ceiling with a mirror placed underneath. The inverted reflection showed him how the arches would naturally form and support themselves. This experiment was the foundation for the design of the forest-like interior with its branching stone columns. One of these original models is preserved and can be seen today in Casa Milà (La Pedrera).

La Sagrada Familia is a unique masterpiece

The Sagrada Familia has been under construction for more than 130 years and is still not finished. The construction faced many setbacks: the Spanish Civil War destroyed many original models and plans, which slowed progress. More recently, the pandemic delayed the expected completion because the project has always been funded mostly through donations and ticket sales.

Is Sagrada Família Worth It?

Absolutely. This is Barcelona’s most iconic monument, and in our opinion, it’s a place that makes you feel something beyond just checking off a sightseeing spot.

Although you can spot the Sagrada Família from several points across the city, its silhouette alone is breathtaking. The real magic happens once you step inside.

The colorful stone forest inside La Sagrada Familia

The interior feels like walking into a stone forest filled with tall columns that rise like trees, and the stained-glass windows fill the space with colors. The sensation is nothing like seeing photos. It’s emotional, overwhelming, and impossible to capture through a lens.

And it’s not just the inside. The exterior itself is a masterpiece. We noticed that every figure carved into the façades has a different meaning that can only be truly appreciated when you see it up close.

How Long To Spend at Sagrada Família?

If you opt for the self-guided audio tour, there are two versions:

  • 45-minute standard tour
  • 25-minute express version.

But in reality, both take longer. We had to stop the audio several times to spot what the narrator was describing, so in total, we spent a little over an hour inside.

Note: Even if you choose the express option, plan at least an hour to walk slowly, take photos, and soak up the details. If you’re more into architecture or spirituality, you could easily spend two hours.

Is Sagrada Familia Free?

No, the Basilica of Sagrada Familia is not free. Tickets start at 29€. While you might get in for free by attending the 9:00 a.m. Mass on Sunday, the line is usually very long. If you really want to visit, I wouldn’t risk it, and I’d just buy the tickets.

Where To Buy Tickets To Sagrada Familia

The best place to book cheaper self-guided tickets to the Sagrada Família is always the official website.

However, if you have more than a day in Barcelona and truly want to understand the history and details behind every design element of this masterpiece, the Basilica, we recommend the Sagrada Familia Skip-the-Line Guided Tour.

Because travelers consistently mention how knowledgeable the guides are, how well-organized the tour is, and how much more they got out of the visit compared to going on their own.

dress code for Sagrada Familia

As with any other religious temple, bring a scarf or jacket to cover bare shoulders and avoid very short clothing.

Visiting Sagrada Família Tips

  • Tickets: Buy in advance because tickets sell out weeks ahead.
  • Interior: If you visit, go inside. That’s where you truly see the details.
  • Exterior safety: The area outside is always crowded with street vendors. It’s also a hotspot for pickpockets. We recommend taking your exterior photos only after passing the security wall, where it’s calmer. The outside vibe wasn’t pleasant with so many vendors.
  • Tours: Download the official app for the self-guided tour. Bring earphones. You can choose a short or long version. Since we were trying to see several places in one day in Barcelona, we chose the shortest one. But we’re planning to return when the cathedral is finally completed to take the full guided tour.

3. Take A Barcelona Bus Turístic Hop On Hop Off Barcelona

The Barcelona Bus Turístic is a hop-on, hop-off bus with two different routes, and with one ticket, you’re allowed to ride both routes on the same day:

  • The blue route
  • The red route

The buses usually run about every 15 minutes, and they stop at most of the famous landmarks around the city. If you’re curious about where these routes go or the specific stops, check out the official Barcelona Bus Turístic route map.

We decided not to use the Barcelona Bus Turístic to get to Park Güell and Sagrada Familia, since we wanted to go there first thing in the morning, before the big crowds arrived.

Instead, we hopped on later in the Sagrada Familia stop and did the entire red route to see the city from above.

Note: Out of all the stops, we only got off at two of them, which we’ll be talking about in more detail below.

Where To Buy Barcelona Bus Turístic Tickets?

We booked our tickets for the Barcelona Bus Turístic on the Get Your Guide website.

  • We recommend booking your ticket in advance because they can sell out, especially in high season.
  • When you buy a ticket online, you’ll get a voucher, which you must show to the guide when boarding the bus.
  • Both printed and mobile copies are accepted.

How Much Is a Hop-On Hop-Off Bus In Barcelona?

The Barcelona Bus Turistic Hop On Hop Off in Barcelona has two types of tickets:

  • 24-hour ticket starting at 33€
  • 48-hour ticket starting at 44€

Note: Your ticket comes with an audio guide and headphones, so you can enjoy the views while learning a bit of the city’s history on the ride.

4. Barcelona Bus Turístic: National Museum Of Art Of Catalonia (MNAC) Stop

Our first stop in the Barcelona Bus Turístic was the National Museum of Art of Catalonia  (MNAC) stop, which is located in the heart of Montjuïc, a beautiful hill area that feels different from the rest of Barcelona.  

Things To Do In Montjuic

In Montjuïc, you’ll get the best spots for panoramic views of the city, and you definitely will disconnect from the busy city vibe. We spotted several people walking their dogs, reading books, and just enjoying the calm vibe.

There are several things to do on Montjuic, from visiting the museum, theater, gardens, or getting on the teleferic, but since we only had one day in Barcelona, we were able to see the two spots we mentioned below.

→National Museum Of Art Of Catalonia

The National Museum of Art of Catalonia is a majestic neoclassic-style building on the hill of Montjuic that you’ll notice as soon as you get off the Barcelona Bus Turístic at the MNAC stop.

We didn’t go inside because of limited time, but just heading to the front terrace was enough to get stunning views of Barcelona.

Note: If you’re visiting Barcelona on Saturday, the museum offers free tickets from 3 pm or all day on the first Sunday of the month, but you need to book the museum tickets in advance.

→Barcelona Pavilion Visit (Mies Van Der Rohe Pavilion)

If you keep walking down the stairs of the National Museum of Art of Catalonia, you’ll find the Barcelona Pavilion.

  • The Barcelona Pavilion was designed by one of our favorite architects, Ludwig Mies van der Rohe.
  • This structure was built in 1929 for the International Exposition as Germany’s national pavilion.
  • Following the exposition, the Pavilion was dismantled and later reconstructed in 1986 using the same type of materials as originally designed.
  • The Barcelona Pavilion broke the traditional design of the time back in the 20th century with the combination of marble, glass, and steel materials and introduced open spaces and minimal ornamentation.

Walking through the space, you really feel the calm, elegance, and modernity it represents. For architecture lovers, this is definitely a stop not to miss.

Note: Check the Barcelona Pavilion special schedule on the official website if you intend to visit Barcelona in August, as on certain days the Pavilion is not open.

5. Barcelona Bus Turístic Hop On Hop Off: Casa Batlló Stop

The next stop we hopped off from the Barcelona Bus Turístic was the Casa Batlló stop, located along Passeig de Gràcia.

  • Passeig de Gràcia is one of the most famous streets in Barcelona, not only for its luxury shops but also for its history.
  • This was where wealthy families lived in the early 20th century, and many of them hired different architects to build the most impressive homes and compete with their neighbors.
  • Today, the street is lined with exclusive boutiques, and we even saw lines of people waiting to get into high-end stores! and some of the most remarkable examples of modernist architecture.
  • Two of the architectural highlights are Gaudí’s Casa Batlló and Casa Milà (La Pedrera), which make this Bus Turístic stop an absolute must.

→Visit Casa Batlló

Right next to the Barcelona Bus Turístic stop stands Casa Batlló, one of Gaudí’s most beloved works. The façade is breathtaking: covered in colorful mosaics (trencadís), with green-framed windows and a roof that resembles the scales of a reptile.

The house originally belonged to the wealthy Batlló family, and Gaudí didn’t build it from scratch. Instead, he completely redesigned and refurbished an existing building, transforming it into the masterpiece we see today.

We didn’t have the chance to visit inside, but if time allows, this is absolutely worth going inside because several visitors claim that the interior experience, filled with light, curved lines, and details, is as impressive as the façade.

→Visit Casa Amatller

Right next door to Casa Batlló is Casa Amatller, designed by Josep Puig i Cadafalch, another prominent 20th-century architect. The façade is impressive as well, but very different from Gaudí’s style because it’s more linear with a stepped roof and a mix of terracotta colors.

We didn’t have the chance to visit inside, but if you want a more intimate connection and explore the architecture at your own pace without feeling rushed, the Casa Amatller isn’t as crowded as other Barcelona landmarks like Casa Batlló, which a lot of people appreciated.

→Visit Casa Milà (La Pedrera)

Just a few blocks away, also on Passeig de Gràcia, is Casa Milà, better known as La Pedrera because of its wavy stone façade.

  • Casa Milà was commissioned by the wealthy Milà family, who wanted a residence that would make everyone envious.
  • Unlike Casa Batlló, this building was designed by Gaudí from the ground up, and it became the last residential project of his career.

We were short on time in Barcelona and could only visit one inside, so we chose Casa Milà because it offers a deeper look into Gaudí’s techniques and vision. Honestly, both are musts if you love architecture.

Note: If you are visiting Casa Milà, you are only one block away from an incredible culinary experience. You might want to check out my full review of eating at the Best Vegan Fine Dining in Barcelona: Xavier Pellicer Restaurant.

Is Casa Mila Worth Visiting Inside?

Absolutely. The stone façade alone makes it stand out from the other buildings around it, and you’ll notice groups of people gathered outside trying to get the perfect photo. But trust us, you need to go inside.

  • This is an audio tour guide, and once you get inside, you’ll take either the stairs or the elevator to get to the rooftop. The visit usually begins on the rooftop, where the famous warrior-shaped chimneys stand guard. The rooftop also features Gaudí’s signature mosaic style (trencadís).
  • From there, you continue down to the attic with its brick arches, where several models are displayed, including the hanging model Gaudí used to calculate the weight distribution for the columns of the Sagrada Família. For me, this was the most fascinating part of the visit.
  • The tour continues into the recreated apartment, furnished as it would have been in the early 20th century, giving you a sense of how the Milà family lived. The interiors feel very organic, with light and dark spaces flowing into each other.

Casa Milà Tips
  • Book online in advance of your visit.
  • Recommend booking at sunset for a more intimate and less crowded experience, plus the weather is better at that time of day.
  • The rooftop floor is covered with steps and slopes, so you need to be careful where you walk, but it’s worth it because on this rooftop, you get spectacular views of the city and even the Sagrada Familia.

Overall: Best Way to See Barcelona In One Day

Although we wished we could have spent more days in Barcelona, having a well-planned itinerary gave us the chance to immerse ourselves in most of the city’s highlights and still enjoy the experience without feeling rushed.
