La Mercè, Barcelona’s biggest annual festival, transforms the city each September with parades, concerts, and dazzling light displays.

Running since the 19th century, the fest honors the city’s patron saint. The Festa Major de Barcelona features traditional Catalan activities along with modern shows, street art, and fireworks.

The program spans four days and features over 500 events.

On September 24th, top attractions open their doors for free, and concerts are held across iconic spots like Plaça Real and Platja Bogatell.

Enjoy traditional parades featuring castellers (human towers), els gegantes (the giant puppets), and correfocs (fire runs). Then, see the mesmerizing drone display that projects stunning images onto the night sky.

Finally, after days of nonstop festivities, marvel at the unforgettable fireworks at Plaça Espanya.

2. Have Fun at PortAventura World

September is a great time to have fun at PortAventura World, the biggest theme park in Spain. With school starting, you’ll share the amazing rides with fewer local families and kids.

Enjoy adrenaline-pumping rides, cool water attractions, and entertaining themed zones. September is the perfect time to ride Shambhala, one of Europe’s tallest roller coasters. And if the sun is too strong for your liking, cool off at the water slides of the Caribe Aquatic Park.

For an extra kick, explore Ferrari Land. The high-speed thrills offer a high-octane experience.

PortAventura World is a perfect summer day trip from Barcelona, only about an hour away from the city.

3. Celebrate Magical Nights at Casa Batlló

The Magical Nights at Casa Batlló are among the best things to do in Barcelona in September

An unforgettable way to spend the warm summer evenings in September in Barcelona is by attending the Magical Nights at Casa Batlló.

One of Gaudí’s most famous buildings becomes the décor of an extraordinary spectacle in summer. The event offers a unique way to immerse yourself in the genius’s architectural masterpiece.

The Magical Nights blend a visit of the “House of Barcelona” with live music at the fairytale rooftop of the building.

You’ll start your enchanting evening with a glass of cava, the famous Catalan sparkling wine. Then, you’ll explore every corner of the unique former residence. Finally, you’ll experience the magic of live music at the legendary roof of Casa Batlló, with the backdrop of Barcelona’s skyline.

4. Explore the Otherworldly Casa Milà at Night

Casa Mila Passeig de Gracia Barcelona
Visiting Casa Mila at night is one of the top things to do in Barcelona in September

The mind-boggling architecture of Casa Mila, also known as La Pedrera, captivates with its curvy lines. 

The last Gaudí building astonishes with its wavy exterior and intricate wrought-iron balconies which make it one of Barcelona’s most recognizable landmarks.

Believe it or not, but despite the unbelievable façade, the crown jewel is Casa Mila’s rooftop.

Towering chimneys, skylights, and vents shaped like an army of soldiers adorn the roof. Or are they actually a futuristic city skyline? I’ll let you decide 😉

However, here’s a fun fact: the unique shapes inspired George Lucas for his iconic Star Wars Stormtroopers.

If you, too, want to be inspired by Gaudi’s imagination, visit the UNESCO World Heritage site in Barcelona in September.

5. Visit the Unfinished Sagrada Familia

You should definitely visit Sagrada Familia in September in Barcelona

Your trip to the Catalan capital won’t be complete without exploring the Sagrada Familia.

September might not be the best time to do so, but it’s still better than Barcelona in July or August.

More than a century since construction started, Gaudí’s most famous building is still unfinished. This means that even if you’ve been to Barcelona before, I bet the basilica got a few more towers since.

Try to visit as early as possible in the morning or enter with the last admission of the day to avoid the heaviest crowds.

💡 Tip: It’s no longer possible to buy your Sagrada Familia ticket in person. The only way to enter Barcelona’s most famous attraction is to get your ticket online!

6. Celebrate the National Day of Catalonia

On September 11th, Barcelona celebrates La Diada Nacional de Catalunya.

A day full of events honors Catalonia’s identity and legacy. The program includes official floral tributes at the Rafael Casanova monument, concerts, cultural performances, and guided visits to iconic landmarks.

Major cultural sites open their doors for free and the city center turns into a bustling rally.

The day ends with large-scale gatherings that reflect Catalonia’s community pride and spirit. If you’re in the center of Barcelona, be mindful of large crowds and public transport delays.

7. Roam All of Spain in Poble Espanyol

Poble Espanyol Barcelona
Exploring Poble Espanyol is among the top things to do in Barcelona in September

At Poble Espanyol, you can explore the diversity of the Spanish regions, architecture, and traditions all in one place.

The unique open-air museum is located on the hillside of Montjuïc. It showcases replicas of iconic buildings from all corners of the country.

Inside the architectural complex, you can roam the cobble-stoned streets, sit at the picturesque squares, and admire the vibrant traditional buildings. You can also attend different workshops and live performances in Poble Espanyol.

My top recommendation is to visit the Fran Daurel Museum. Inside, you can marvel at modern art from famous painters like Pablo Picasso, Salvador Dalí, and Joan Miró.

8. Watch the Sunset at Park Güell

Visiting Park Güell in Barcelona in September is a great idea

September is still busy at Park Güell but I have a trick for you to escape the crowds.

Buy your ticket for the last possible admission of the day. Once you’re inside Gaudí’s creation, wait for the tourists to exit and shoot your photos in peace.

While waiting, explore the farthest corners of the park. You can even have a picnic in the designated areas.

Then, marvel at the intricate mosaics, the mind-bending benches, and the unique viaduct.

When the tourists leave, snap a selfie with the iconic salamander while enjoying the stunning sunset over Barcelona.

9. Marvel at Barcelona‘s Modernist Architecture

Recinte Modernista de Sant Pau Barcelona
Recinte Modernista de Sant Pau is probably my favorite Modernist building in Barcelona

Barcelona is the best city on the planet to see the fascinating Modernist architectural style. It gained popularity in the late-19th and early-20th centuries.

The Catalan capital owes its architectural glory not only to the world-renowned Antoni Gaudi. Other architectural geniuses worked in the same period as him and left their unique cultural treasures.

You should check out the UNESCO World Heritage Sites Recinte Modernista de Sant Pau and Palau de la Musica Catalana, designed by Lluís Domènech i Montaner.

His works incorporate mythical, religious, and modern figures, topped by mind-bending arches and spikes, and sprinkled with glazed tiles and stained glass.

Another architect whose works you should also explore is Josep Puig i Cadafalch. Check out his most distinguished creations, Casa de les Punxes (House of the Spikes) and Casa Amatller (next to Gaudi’s Casa Batlló).

10. Relax on the Beaches Along the Costa Brava

September’s long days and warm weather provide the perfect opportunity to explore the gorgeous Costa Brava.

Discover medieval fortresses and picturesque old towns. Chill at stunning coves along the coast. Savor delectable seafood at the beach bars. For an extra layer of adventure, join a sea kayaking tour of the Costa Brava.

Here are my favorite spots for beach outings:

  • Tossa de Mar: This picturesque town attracts with its medieval castle, Roman ruins, and peaceful beaches.
  • Aigua Blava: The small but stunning cove is famous for its clear waters and dramatic cliffs. The beach is great for swimming, snorkeling, and sunbathing.
  • Blanes: The gateway to the Costa Brava features beautiful botanical gardens, family-friendly beaches, and lively summer festivals.

11. Party at Festa Major de la Barceloneta

Right after the end of La Merce, you can enjoy the lively Festa Major de la Barceloneta.

Head down to the beachside neighborhood for a vibrant celebration filled with parades, live music, and classic Catalan traditions.

The fishing district sure knows how to throw a party. The streets light up with decorations, and beachside bars and food stalls keep the party going all day and night.

You can also experience castellers (human towers) and correfocs (fire runs), and get a taste of Barcelona’s coastal charm and community spirit.

12. Chill at Barcelona’s Best Rooftops

If you wish to explore a less-visited but stunning Gaudi creation, Colonia Güell is the place to go.

The UNESCO World Heritage site is a small Modernist village designed to house factory workers. You’ll find it 20 minutes from Barcelona.

At the Colonia, you can explore the outstanding Crypt of Colonia Güell, where you can admire Gaudí’s early talent. His signature style is revealed in the natural forms and elaborate details.

Don’t skip roaming around the quaint village, where you’ll encounter beautiful Modernist homes and community buildings.

The most characteristic sign of this architectural style is the use of exposed bricks, iron, and ceramics to create flowing lines mimicking the organic world.

15. Discover the Best Beaches of Barcelona

September still offers great swimming conditions at the beaches of Barcelona.  

The beach bars (chiringuitos) are not as busy as in July and August, and continue serving delicious food and refreshing drinks.

You should still avoid going to the city beaches, such as Barceloneta and Somorrostro Beach. In September, the local Bogatell and Mar Bella Beaches start to get less crowded, so you might want to try your luck there.

Still, I recommend you head to the long-stretched Playa Castelldefelds or Ocata Beach. You’ll find plenty of things to do and beach bars to try out there.

16. Experience Festa Major del Poblenou

Poblenou, one of the most vibrant and unique neighborhoods of Barcelona, hosts its Festa Major in September.

The lively festival mixes traditional Catalan events with a modern, artsy twist – unique to the district’s creative vibe.

You can expect colorful street decorations, live concerts, open-air movie screenings, and street food stalls to keep your energy levels high.

The highlights in the program include the traditional correfoc (fire run), castellers (human towers), and els gigantes (giant puppets). The dance parties spill out onto the streets and follow the parade, then continue late into the night.

17. See Barcelona from Land, Air, and Sea

Among to top things to do in Barcelona in September is discovering the city on an exhilarating “land, air, and sea tour”.

The unique combo provides a thrilling experience. It also gives you a great way to escape the crowds. Plus, you can witness the beauty of Barcelona from every vantage point!

Start with a guided walking tour of the historic center before heading to the heliport. A short but unforgettable flight over the city will show you Barcelona’s most iconic landmarks, the gorgeous coast, and the majestic Montjuïc.

After the flight, you’ll get on a sailing boat from the Old Port and explore Barcelona from the water, too.

18. Tour Three Countries in One Day

My top recommendation? Visit three countries in a single day. (Yes, you’ll have the time!)

Join this small-group tour and an unforgettable journey through Spain, France, and Andorra is guaranteed.

The first stop of the trip is the medieval town of Baga in the Catalan Pyrenees.

Next, you’ll cross the border into France. There, you’ll visit the charming Mont-Louis, a UNESCO World Heritage site.

Indulge in the culinary creations prepared by top chefs. Meanwhile, you can learn about the constellations in the night sky above you.

This is an exquisite mix of fine dining with a pinch of magic, mystery, and romance.

20. Sail Along the Coast of Barcelona

In September, you’ll still have a couple more days to swim at the Piscina Municipal de Montjuïc while watching over the panorama of Barcelona.

The stunning facility closes on September 5. Enjoy its world-class swimming experience and the breathtaking views of the city below you.

The 25-meter pool features diving boards and was originally built for the 1992 Barcelona Olympics.

Don’t forget to bring a towel or a mat as there are no sun loungers available at the pool. A small bar serves food and drinks, but my recommendation is to bring your own snacks.

22. Picnic at Parc de la Ciutadella

The most beautiful green space in Barcelona, Parc de la Ciutadella, is the best escape from the heat and the tourists.

In the park, you can also rent a boat to paddle around the lake in the middle, have a long, chill picnic, or simply stretch under the trees and enjoy a moment of peace.

23. Enjoy Thrill Rides at Tibidabo Amusement Park

Tibidabo’s great views and thrill rides make it a great thing to do in Barcelona in September

Tibidabo Amusement Park stands at 1,680 ft. (512 m) high and offers great panoramas over Barcelona paired with thrill rides.

The historic park has been functional since 1901 and blends vintage charm with modern functionality.

The classic Avió airplane is the oldest in the park, while the newest attraction, Merlí, started running in 2024. Both provide great views but the 52-m (171-ft.) freefall tower will challenge even the bravest thrill-seeker.

For a more chill experience, enjoy the views from the vintage Ferris wheel or visit the Sacred Heart of Jesus Church.

24. Dance the Night Away at BAM Festival

If you’re into fresh sounds and underground vibes, BAM Festival is the place to be.

The event is part of the festivities celebrating La Mercè (see #1).

The epic music fest has taken over Barcelona every September since 1993, with stages popping up all over the city. Iconic locations like Plaça Reial, Platja de Bogatell, and Parc del Fòrum host up-and-coming bands and performers.
