21 Things To Do in Barcelona: Iconic Landmarks & Hidden Gems

Barcelona is an incredibly beautiful city with a relaxed, friendly atmosphere that made us fall in love with it almost immediately.

The unique mix of Gaudí’s imaginative architecture, vibrant neighborhoods, seaside views, and amazing food makes it one of the most memorable destinations in Europe.

We spent 5 days in Barcelona, and since it was already our second visit, we had the chance to explore both the famous highlights and some less obvious places.

From iconic landmarks like the Sagrada Família and Park Güell to scenic viewpoints, lively markets, and charming historic streets, the city offers an incredible variety of experiences.

Choosing the right base can make exploring much easier, especially if you want to minimize travel time between attractions and enjoy the atmosphere of your neighborhood in the evenings.

Below, you’ll find the best things to do in Barcelona based on our visit, including must-see sights, viewpoints, hidden gems, and practical tips to help you plan your itinerary efficiently.

Iconic Architecture & Landmarks

1. Sagrada Familia

The Sagrada Família is one of the most famous buildings in the world and easily the most unique architecture we’ve ever seen with our own eyes.

Designed by Antoni Gaudí, construction started in 1882 and is still ongoing today — more than 140 years later.

Even from the outside, the level of detail is absolutely incredible. Every façade tells a story and is filled with symbolism, sculptures, and intricate carvings, many inspired by nature and religious themes.

We visited on a guided tour, which helped us better understand the deeper meaning behind the design.

Once we entered, the interior honestly took our breath away. The main hall is extremely tall and filled with colorful stained glass windows, which decorate the walls in different shades of blue, green, orange, and red.

As sunlight passes through the glass, the colors slowly change throughout the day, creating a truly magical atmosphere.

The tall columns resemble tree trunks, branching out towards the ceiling and making the space feel almost like a forest made of stone and light. It’s unlike any church we’ve ever visited and definitely one of the highlights of Barcelona.

Tip: Book tickets in advance and choose a morning or late afternoon time slot for softer light inside the basilica.

2. Park Güell

Park Güell is one of the most famous parks in Barcelona, spread across a hillside and filled with Gaudí’s signature playful architecture. The park perfectly combines nature, viewpoints, and colorful design, making it one of the most photogenic places in the city.

Right at the main entrance, you’ll find the two iconic fairytale-like buildings that look almost like gingerbread houses. Between them sits the famous mosaic lizard fountain (El Drac), one of the most recognizable symbols of Barcelona.

From the entrance, a grand staircase leads uphill to one of the park’s highlights — the large terrace supported by stone columns.

The terrace is lined with Gaudí’s famous curved mosaic benches, often referred to as the “Gaudí balconies,” offering beautiful views over the main entrance and the city beyond. The colorful ceramic tiles and unique shapes make this one of the most popular photo spots in the park.

As we continued walking uphill, we discovered several viewpoints and quieter paths, where the atmosphere feels much more relaxed compared to the busy central area. The elevated position of the park provides wide views over Barcelona.

It’s worth noting that the only tourist entrance is located at the bottom of the park near the monumental zone. While the map may show several access points, most of the upper entrances are reserved for local residents.

3. Recinte Modernista de Sant Pau

The Recinte Modernista de Sant Pau was one of the biggest surprises of our trip and easily one of the most beautiful architectural complexes in Barcelona.

Despite its incredible design, it’s much less crowded than other famous landmarks, which makes the visit even more enjoyable.

Originally built as a hospital in the early 20th century, the complex was designed by architect Lluís Domènech i Montaner, one of the key figures of Catalan Modernism.

The site consists of multiple beautifully decorated buildings connected by underground passages, surrounded by gardens and open spaces.

What makes Sant Pau so special is the level of detail visible everywhere you look — colorful mosaics, sculptures, decorative tiles, stained glass, and elegant facades.

Tip: The complex is located about a 10–15 minute walk from the Sagrada Família, so it’s easy to combine both into one itinerary.

4. Palau de la Música Catalana

The Palau de la Música Catalana is one of the most stunning concert halls we’ve ever seen and another masterpiece of Catalan Modernism, designed by architect Lluís Domènech i Montaner.

Even though it’s less famous than Gaudí’s buildings, the interior is just as impressive — if not more. From the outside, the building already stands out thanks to its rich decorations, colorful mosaics, sculptures, and detailed façade.

The main concert hall is absolutely breathtaking. The space is filled with ornate details, vibrant colors, stained glass, and intricate sculptures. The centerpiece is the spectacular glass ceiling dome, designed to let natural light illuminate the hall.

Even if you don’t attend a concert, visiting the Palau de la Música Catalana is absolutely worth it for its architecture alone.

5. Montjuïc

Montjuïc is a large hill overlooking Barcelona, offering a mix of beautiful viewpoints, historic buildings, gardens, and cultural attractions.

One of the main highlights here is the impressive National Palace (Palau Nacional), a grand building constructed for the 1929 International Exhibition.

From the front of the palace, wide staircases and terraces lead down towards the city, creating one of the most iconic viewpoints in Barcelona. The elevated position provides beautiful panoramic views, especially during sunset.

In front of the palace lies the famous Magic Fountain, known for its evening shows combining water, lights, and music.

We especially enjoyed walking slowly up the stairs, stopping at different levels to admire the views.

Montjuïc itself offers many more places to explore, including gardens, viewpoints, and museums. We spent a few hours here walking around the parks.

6. La Pedrera – Casa Milà

La Pedrera – Casa Milà is one of Gaudí’s most famous buildings and a great example of his completely unique architectural style. Built between 1906 and 1912, the building was originally designed as a residential apartment house, but today it’s one of the most visited landmarks in Barcelona.

From the outside, the façade immediately stands out thanks to its wave-like stone shape, which gives the building a very organic appearance.

Unlike traditional buildings with straight lines, Gaudí designed Casa Milà to resemble a natural rock formation, which is why locals nicknamed it “La Pedrera” (the stone quarry).

One of the highlights of our visit was the famous rooftop terrace, with unusual chimney structures that look almost like sculptures or futuristic warriors. We also loved the beautiful views over Barcelona.

7. Casa Batlló

Casa Batlló is one of Gaudí’s most imaginative creations and easily one of the most fascinating buildings in Barcelona. Located on the famous Passeig de Gràcia, the house stands out immediately thanks to its colorful façade, organic shapes, and almost surreal appearance.

The exterior is often described as resembling the skin of a dragon, with shimmering mosaic tiles in shades of blue, green, and orange. The balconies look almost like masks, while the curved lines make the entire building look different from anything else.

Inside, the attention to detail is just as impressive. Our favorite part was the Gaudí Cube, a modern immersive installationn which surrounded us with moving projections of Gaudí’s mind through different shapes and colors.

Since it’s one of the most popular attractions in the city, you should definitely buy your ticket in advance.

8. Cathedral of Barcelona

The Cathedral of Barcelona is one of the most impressive Gothic buildings in the city. Located in the heart of the Gothic Quarter, the cathedral stands out with its dramatic façade, detailed carvings, and tall spires that make it look almost fairytale-like.

From the outside, the amount of detail is incredible. Inside, you can see high vaulted ceilings, stained glass windows, and beautifully decorated chapels.

If you take the elevator to the rooftop, you’ll get nice views over the Gothic Quarter, with the cathedral’s towers visible up close.

9. Palau Güell

Palau Güell is one of Gaudí’s earlier works and often overlooked compared to his more famous buildings, but it’s definitely worth visiting — especially if you enjoy architecture and design details.

From the outside, the building looks relatively simple and darker compared to Casa Batlló or Casa Milà, but it’s the interior that shows Gaudí’s creativity.

The highlight is the impressive central hall, featuring a very high ceiling. One of the most interesting parts is the rooftop terrace, where you’ll find a collection of colorful mosaic-covered chimneys.

Each chimney has a unique shape and decoration, making the rooftop feel almost like an outdoor gallery. This is slightly visible also from the outside.

Parks & Scenic Viewpoints

10. Tibidabo

While getting to Tibidabo takes a bit more effort, it’s absolutely worth it.

Located high above the city, Tibidabo offers some of the best panoramic views in Barcelona. We took the Vallvidrera funicular, which was already a fun experience and felt like a small adventure before even reaching the top.

At the summit, there are two main highlights — the historic Tibidabo Amusement Park and the beautiful Temple of the Sacred Heart of Jesus (Sagrat Cor) basilica.

The theme park is one of the oldest in Europe and offers several rides with incredible views over the city and coastline. Even if you don’t plan to go on rides, the atmosphere is very unique thanks to the elevated location.

We personally came mainly for the basilica, which looks stunning with its detailed architecture and impressive position on top of the mountain. The visit inside the church is free, but you can pay around €7 to access the top of the basilica.

The highlight for us was the large upper terrace, which offers spectacular panoramic views over Barcelona. It’s easily one of the best sunset spots in the city, as you can see the skyline, coastline, and surrounding hills slowly changing colors as the sun sets.

Tip: Allow extra travel time when planning your visit, as reaching Tibidabo requires combining metro, train, bus and funicular. The Vallvidrera funicular is covered by T-Usual.

11. Parc del Guinardó

Parc del Guinardó is a place you won’t find in many travel guides, yet it definitely deserves a spot on this list. It ended up being one of our favorite places in Barcelona, mainly because of its calm and local atmosphere.

The park feels very peaceful, with very few tourists, and it’s clear that this is where locals come for evening walks, runs, or walks with their dogs. Compared to some of the busier attractions in the city, the relaxed vibe here was a refreshing change.

What surprised us most were the beautiful views over Barcelona, including a great perspective of the Sagrada Família in the distance.

Because the park is located on a hillside, several viewpoints open up as you walk higher. We liked it so much that we came back again for sunset, when the light over the city looks especially beautiful.

Inside the park, you’ll also find Pont de Mühlberg, a simple wooden bridge surrounded by greenery, adding to the feeling that you’re somewhere in nature rather than in a large city.

Our favorite part was exactly this contrast — the park feels almost like being outside the city, even though it’s still relatively close to major sights like Park Güell. It’s also located near the famous Bunkers del Carmel, so it’s easy to combine both places in one visit.

12. Bunkers del Carmen

Bunkers del Carmel is definitely one of the more unusual attractions in Barcelona. The site consists of old concrete bunkers originally built during the Spanish Civil War, which today are covered in street art and graffiti.

The main reason people come here is simple — the 360° panoramic views over Barcelona are incredible. From the top, you can clearly see the city skyline, the sea in the distance, and landmarks such as the Sagrada Família.

It’s popular with both locals and visitors, so don’t expect to have the viewpoint entirely to yourself. The atmosphere is relaxed, with people sitting on the concrete structures, taking photos, or simply enjoying the scenery.

Even though this would normally be a perfect sunset location, the area is monitored by police, who usually ask visitors to leave shortly before sunset, so it’s not always possible to stay until the very last light.

Tip: Visit a bit late in the afternoon to enjoy the views without rushing, and combine it with nearby Parc del Guinardó for sunset.

13. Jardins del Mirador

Jardins del Mirador is another hidden gem that many visitors overlook, even though it’s located on the popular Montjuïc hill. Compared to the busy areas around the National Palace, these gardens feel incredibly peaceful, green, and relaxing.

The space is beautifully maintained, with lush greenery, shaded paths, and a beautiful fountain, creating a calm atmosphere that feels far away from the busy city streets.

During our visit, an older man was playing guitar and singing nearby, which made the moment even more special while we were enjoying the views.

From the garden terraces, you’ll get beautiful views over Barcelona and the port, making this a perfect spot to slow down for a moment and take in the scenery.

What we liked most is that the garden feels quite undiscovered, even though it’s located close to major attractions on Montjuïc.

14. Ciutadella Park

Ciutadella Park is definitely busier than many of the other parks on this list, but it’s still a very pleasant place to take a break from sightseeing. The park is a popular gathering spot for locals, especially in the afternoon and early evening.

One of the main highlights is the small lake with ducks, where you can either sit on a nearby bench and relax or even rent a small rowboat for a peaceful ride on the water. The atmosphere here feels lively but still relaxed, with people enjoying picnics, walks, or simply spending time outdoors.

Just a short walk away, you’ll find one of the most spectacular fountains in Barcelona — the Cascada Monumental. The fountain is richly decorated with statues, staircases, arches, and golden details, making it look more like a palace than a typical park fountain.

There are often ducks, geese, and even turtles swimming in the water.

In the evening, the fountain is sometimes illuminated, creating an even more beautiful atmosphere. The surrounding area is often filled with street musicians.

15. Barceloneta Beach

Barceloneta Beach probably needs no introduction — it’s the main city beach and one of the most lively places in Barcelona. Located just a short distance from the historic center, it’s very easy to combine with sightseeing.

We walked along the long promenade, which stretches past restaurants, bars, and beach areas, and explored most of the coastline. The atmosphere is always vibrant, with locals coming here to relax, meet friends, play beach volleyball, cycle, or simply enjoy the sea views.

During our visit, we even saw a few surfers trying to catch waves. While Barceloneta isn’t considered a traditional surf destination, windy days can create waves strong enough for experienced surfers, although it’s not ideal for beginners.

After a full day of walking around the city, we really enjoyed slowing down here and just spending some time by the sea. Especially in the warmer months, Barceloneta is a great place for swimming or watching the sunset.

Historic Areas & Hidden Gems

16. Gothic Quarter

The Gothic Quarter is one of the most atmospheric parts of Barcelona and a place where the city’s history truly comes to life.

The area is known for its narrow medieval streets, hidden squares, stone buildings, and historic architecture. The best way to explore is with a camera in your hand, eyes wide open and without a fixed plan.

Walking through the small alleys felt almost like stepping back in time. Around almost every corner, you’ll find small cafés, boutique shops, street musicians, quiet courtyards and plenty of photo spots.

17. El Born

El Born is known for its boutique shops, art galleries, cafés, and restaurants, making it a great place to explore both during the day and in the evening.

We enjoyed simply walking through its narrow streets and discovering small local businesses and hidden corners. The neighborhood feels slightly more polished compared to the Gothic Quarter, but still with plenty of character.

El Born is also home to Santa Maria del Mar, one of the most beautiful churches in Barcelona, and is located close to Ciutadella Park, making it easy to combine both.

18. La Rambla

La Rambla is one of the most famous streets in Barcelona, stretching from Plaça de Catalunya down to the sea. The wide boulevard is lined with shops, cafés, street performers, and historic buildings, creating a lively atmosphere throughout the day.

During our visit in March 2026, large parts of La Rambla were unfortunately under construction, which made the experience slightly less enjoyable due to limited walking space and ongoing works.

Despite that, we still appreciated the variety of restaurants, bars, and small shops located along the street. It’s still a place most visitors pass through at least once, especially because many attractions are located nearby.

19. Plaza Reial

Located just off La Rambla, Plaça Reial is a beautiful square surrounded by elegant buildings with arcades. The palm trees, symmetrical layout, and relaxed atmosphere make it a great place to stop for a break.

At the center of the square stands the impressive Three Graces fountain, decorated with classical sculptures. Around the square, you’ll find many restaurants and bars with outdoor seating, making it a popular spot for lunch, coffee, or a glass of sangria.

20. Mercat de la Boqueria

Mercat de la Boqueria is one of the most famous food markets in Europe. While many visitors describe it as overcrowded or touristy, we actually think this lively atmosphere is part of its charm.

The market is filled with stalls offering traditional Spanish specialties, including paella, jamón (ham), salami, cheese, olives, seafood, and tapas. You’ll also find many stands selling fresh fruit juices, smoothies, and cups of sliced fruit, which reminded us a bit of the street food markets we visited in Asia.

It’s a great place to try a variety of local flavors in one spot, whether you’re looking for a quick snack or a small meal.

21. The World Comes to Life with Each Kiss mural

“The World Comes to Life with Each Kiss” is a beautiful photo mosaic mural located near the Cathedral of Barcelona. From a distance, the artwork looks like a romantic image of a kiss, but when you get closer, you’ll notice it’s made up of thousands of small photos.

Each photo represents moments of freedom and everyday life, symbolizing shared human experiences. The mural was created as part of a project celebrating freedom and expression.

It’s a relatively small stop, but definitely worth visiting if you’re already exploring the Gothic Quarter, especially if you enjoy discovering small artistic details around the city.

Tip: Step closer to see the individual photos that form the mosaic — it’s easy to miss this detail at first glance.

Where to stay

During our stay, we chose Attica21 Barcelona Mar, and overall we were very happy with the experience. While the hotel is located slightly away from the main attractions, it’s close to the metro.

We especially appreciated how spacious the room was. The interior felt modern, clean, and well equipped, making it a comfortable base after long days of exploring.

The highlight of the hotel is definitely the rooftop terrace, which offers beautiful views over the city, as well as a rooftop pool — a great place to relax, especially in warmer months.

Getting around Barcelona

Getting around Barcelona is very easy thanks to its reliable and well-connected public transport system.

We mainly used the metro, which worked perfectly for reaching most attractions quickly and efficiently. The network covers a large part of the city, and trains run frequently throughout the day.

In some cases, buses or funiculars can be even more practical, especially when visiting places located on hills such as Tibidabo or Montjuïc. We used funicular connections a few times, and it was not only convenient but also part of the experience.

We highly recommend avoiding the tourist-focused Hola Barcelona card, which is usually more expensive than necessary. Instead, a better option is the T-Usual ticket, which offers unlimited public transport for 30 days within the selected zones for a very reasonable price (around €21–€40 depending on zones).

Where to eat

Here are some places we personally tried and would happily recommend:

• Bar Restaurant Lepant – located close to Sagrada Família, serves classic Spanish dishes including paella and tapas. Prices are slightly higher due to the location, but the food was very tasty and the staff was incredibly friendly.
• Sagra Specialty Coffee & Brunch – one of the best coffees we had during our trip. Great spot for breakfast or brunch with quality coffee and a relaxed atmosphere.
• Pizza Local – excellent Neapolitan pizza made with quality ingredients. Friendly staff and very good dough made this one of our favorite casual dinner spots.
• Burritos San Pere – offers customizable burritos with fresh ingredients and very good flavor. Perfect for a quick and filling meal.
• Xurreria San Román – incredibly tasty and fresh churros, both classic and filled versions, served with rich hot chocolate. Much better than some more overrated spots.
• Cake Me – cheesecake for €0.99 that’s actually very good. Simple, affordable, and delicious.

Final Thoughts

Barcelona quickly became one of our favorite cities in Europe. The combination of unique Gaudí architecture, lively neighborhoods, scenic viewpoints, beaches, and incredible food makes it a destination that offers something for almost every type of traveler.

We spent 5 days in Barcelona, and highlights for us included the breathtaking Sagrada Família, colorful Park Güell, sunset views from Tibidabo, and the peaceful atmosphere of Parc del Guinardó.

Choosing the right neighborhood can also make a big difference in how easily you move between attractions and how enjoyable your stay feels overall.
