Gaudi's architectural masterpieces in Park Güell in Barcelona.

Things to do in  Barcelona

In Gaudí we trust

Vibrant and modern with an ancient heritage, Spain’s second city and Catalonia’s de facto capital enchants even at its busiest. For most travelers, Gaudí’s sinuous, curving architecture tops the list of things to do in Barcelona, with UNESCO World Heritage-listed masterworks including Park Güell, Casa Batllo, and the unfinished Sagrada Familia cathedral. Yet there’s much to discover in the city’s walkable old town while tapas, wine, and food tours beckon, alongside sailing, beaches, and bar-hopping. Top Barcelona day trips include Montserrat Mountain, medieval Girona, and the tiny nation of Andorra.

Here, get your guide to Barcelona’s best attractions, tours, and more.

Top 15 attractions in Barcelona

Sagrada Familia

star-562,528
Sagrada Familia, a UNESCO World Heritage site and Antoni Gaudi’s magnum opus, is the most iconic structure in Barcelona (and the most popular, with nearly 3 million visitors per year). Construction has been ongoing for more than 130 years, and the surreal structure, with its rainbow-hued stained glass windows, is slated for completion in 2026. Even in its unfinished state, it remains an absolute must-see for every visitor to the Catalan capital.More

Park Güell

star-527,555
Antoni Gaudí spent 15 years designing and building the whimsical fountains, mosaic benches, pedestrian walkways, and gingerbread house-like buildings within Park Güell, one of the seven Works of Antoni Gaudí locations that together make up a UNESCO World Heritage site. Along with the Sagrada Familia, the hilltop public park sits at the top of Barcelona’s must-see list, and for good reason. The art nouveau wonderland adorns many a postcard of the city.More

Casa Batlló

star-533,145
One of Barcelona’s most fanciful buildings, the elaborate Casa Batlló was built by celebrated Catalan architect Antoni Gaudí and is nicknamed the “House of Bones” for its contorted window frames and skeletal pillars. Casa Batlló’s interior is equally mind-boggling, featuring rippled walls, exquisite tile work, and sculpted fireplaces.More

Gothic Quarter (Barri Gotic)

star-538,356
Barcelona's Gothic Quarter (Barri Gotic) dates back to the Middle Ages, and the neighborhood’s age is evident in its narrow winding roads, shaded plazas, and beautiful architecture (including three major cathedrals). Passersby find gems tucked away in the nooks and crannies—think trendy restaurants, chic bars, and boutique shops. The area's proximity to the La Rambla pedestrian mall also contributes to its popularity among the young, nightlife-loving crowd.More

La Pedrera - Casa Milà

star-534,864
One of Antoni Gaudí’s most intriguing creations, the spectacular Casa Milà—commonly referred to as La Pedrera (The Quarry) because of its wave-like stone exterior—caused some controversy among critics when it was first unveiled back in 1910. Today, however, it's considered a masterpiece of Catalan Modernisme, with gaggles of visitors coming to see its surreal sculptural roof terrace, the re-created early 20th-century interiors, and the attic-level Espai Gaudí exhibit, which is devoted to the great Catalan architect’s work.More

Passeig de Gracia

star-528,659
Passeig de Gràcia is one of the most beautiful—and expensive—avenues that runs through the center of Barcelona. The thoroughfare links the Placa Catalunya in the Eixample district to the eponymous Gracia neighborhood, and is home to a number of fantastic modernista and art nouveau buildings, including some stunners by Antoni Gaudí.More

Las Ramblas

star-525,698
Barcelona's most famous street, Las Ramblas runs from the Columbus Monument in Port Vell to Plaça de Catalunya. To walk its tree-shaded pedestrian expanse is to be inundated with sensation: souvenir hawkers selling beach blankets and trinkets, street performers posing for selfies with tourists, florists displaying their arrangements, restaurants serving tapas and paella at alfresco tables, and artists painting caricatures for passersby. It's a microcosm of Barcelona, and it's almost always busy, day or night.More

Port Olímpic

star-518,800
Flanked by the Torre Mapfre and Hotel Arts skyscrapers, the Port Olímpic was built as part of the area’s redevelopment in preparation for the 1992 Olympics. With its proximity to the beach and its iconic public art (including Frank Gehry’s Peix), it has become one of the most popular leisure areas in the city and a busy marina.More

Barcelona Cathedral (Catedral de Barcelona)

star-522,594
Standing tall over a medieval square in the center of the Gothic Quarter, the Barcelona Cathedral (Catedral de Barcelona) is the seat of the Archbishop of Spain and a major landmark of the city. The cathedral is known for its 14th-century cloister full of palm trees and a Gothic portico where 13 geese wander.More

Montserrat Mountain

star-545,115
Located about 30 miles (50 km) northwest of Barcelona is Montserrat Mountain, the 'Serrated Mountain.' This unique rock formation, sawed and sculpted by thousands of years of wind and rain, is most famously home to a Benedictine monastery, an important Catholic pilgrimage spot thanks to its 12th-century wooden statue of La Moreneta (The Black Madonna), Catalonia's patron saint. Aside from its religious and cultural importance, the mountain also boasts unbeatable views from its peaks.More

El Born

star-517,915
One of the oldest neighborhoods in Barcelona is also one of the trendiest. El Born features character-rich streets lined with tapas bars, quaint bistros, and artsy clubs that give this area a bohemian vibe. Its proximity to many of Barcelona’s top attractions, such as Las Ramblas and the Gothic Quarter, make El Born an ideal place to stay.More

Ciutadella Park (Parc de la Ciutadella)

star-518,130
Barcelona’s oldest and most popular park, Ciutadella Park (Parc de la Ciutadella), is a picturesque expanse of greenery with several attractions. Its landmark Arc de Triomf, designed by Josep Vilaseca i Casanovas, serves as the monumental gateway to the northern entrance of the park, which is also home to a boating lake, the Barcelona Zoo, Catalan Parliament, two museums, and a much-celebrated series of sculptures.More

St. Mary of the Sea Cathedral (Basilica de Santa Maria del Mar)

star-522,639
St. Mary of the Sea Cathedral (Basilica de Santa Maria del Mar) stands at the end of Passeig del Born as one of Barcelona’s most magnificent Catalan Gothic churches. Built in the 14th century, the cathedral is characterized by its architectural elegance and harmony. A highlight is the 15th-century stained-glass rose window.More

Catalunya Square (Plaça de Catalunya)

star-520,677
Old and new Barcelona meet in Catalunya Square (Plaça de Catalunya), the famous plaza in the heart of the city. Two massive avenues, La Rambla and Passeig de Gracia, converge here too, as do many walking tours and other groups. The square is located near some of Barcelona’s top attractions and is filled with cafés, bars, and restaurants.More

Montjuïc Castle (Castell de Montjuïc)

star-512,949
Looming dramatically over the Barcelona skyline, Montjuïc Castle (Castell de Montjuïc) is a 17th-century military fortress perched atop Montjuïc Mountain. After a tumultuous history, including various wars, the site now functions as a municipal facility and hosts cultural events—and offers great views of the city and beyond.More

All about Barcelona

When to visit

During the high season, Barcelona is crowded and often rowdy with tourists looking to party. For a quieter visit, shoulder seasons are the way to go, from March through April and September through October. If traveling during the spring holidays, book well ahead for Easter. Beach bar season begins in May, but the water may feel chilly, so opt for September if swimming is on your Barcelona bucket list.

Getting around

With buses, trams, a metro, and local trains to choose from, getting around Barcelona is simple. The Hola Barcelona travel card is designed for travelers and offers unlimited rides for periods of 2-5 days. Or, buy a T-Casual ticket with 10 separate journeys in the zones of your choice. A hop-on hop-off bus service covers the top attractions on two separate routes, and a range of bike paths offer options if you’re looking to pedal your way through the city.

Traveler tips

Tapas is a must when visiting Barcelona. Head to Quimet & Quimet, a tiny, standing-room only space that’s been family-owned since 1914: Open-faced sandwiches (montaditos) and fine canned seafood (conservas) are perfect partners for wines, vermouths, and sherry. If you’re looking to bring home a taste of the city, choose from thousands of fine wines—plus cheese, cured meats, and more—at heritage wine merchant Vila Viniteca.

A local’s pocket guide to Barcelona

Monica Nunez

Monica is a Viator account manager based in Barcelona, where you’ll find her walking around the Montjuic hill, shopping in Paseo de Gracia, or discovering new restaurants.

The first thing you should do in Barcelona is...

get lost in the narrow streets of the Gothic Quarter and the El Born neighborhood.

A perfect Saturday in Barcelona...

starts with drinks at Salts in Montjuic, followed by a stop at the beach, a seafood lunch in La Barceloneta, and a cocktail at a chiringuito (beach bar). Finish your day with dinner in El Born.

One touristy thing that lives up to the hype is...

La Sagrada Familia. It’s a very popular attraction, but you won't regret stopping by. And don’t forget to go inside to discover the magical colorful interior.

To discover the "real" Barcelona...

have vermouth and tapas on a terrace in the Gracia neighborhood. There’s always a great atmosphere.

For the best view of the city...

Bunkers del Carmel viewpoint offers a 360-degree view of the entire city and the sea. It’s normally busy and it’s quite far away from the center, but the amazing view is worth it.

One thing people get wrong...

eating in La Rambla. It’s usually overpriced and not great quality.
