20 Things to Do in Barcelona: Essential Guide 2026

Barcelona is a city that has it all: Gaudí’s architecture, medieval neighborhoods, beach, mountains and a street life that hooks you. We know it well: we lived on the Costa Brava for several seasons, in Lloret de Mar and Portbou, and Barcelona was often our getaway, to catch up with friends or simply to wander around it with no plan.

In this guide we tell you about the best things to do in Barcelona: the 20 essential places, with our tricks (like the best free viewpoint in the city), prices updated for 2026 and some important changes, such as Park Güell’s new ticketing system.

Summary: things to do in Barcelona

1. The Sagrada Familia

Gaudí’s masterpiece is astonishing and unmissable. In our years of travel we’ve seen countless basilicas, but this one is truly unique: the natural light pouring through the colored stained-glass windows leaves you speechless. Our advice: walk all the way around the outside before going in, because each facade is completely different (look at the one on Carrer de la Marina and the one on Sardenya).

Tickets are sold online only. We bought ours two days ahead and that was enough, but in high season it’s best to book further in advance. Opening hours change with the season (from April to September, Monday to Friday from 9:00 to 20:00).

2. Park Güell

The park where Gaudí unleashed all his ingenuity, a World Heritage Site: the Nature Square with its undulating bench, the dragon staircase and the Hypostyle Room with its columns.

Heads-up, this has changed: you used to be able to get in for free first thing in the morning or late in the day, but today visitor tickets (€18) are sold with an assigned time slot between 9:30 and 19:30, and the early-morning and evening slots are reserved for residents. You need to buy online in advance.

3. The Gothic Quarter

Narrow medieval streets that, for us, you have to walk with no plan: the best thing is to get lost. Don’t miss Plaça del Rei, the Pont del Bisbe (the most photographed bridge in the neighborhood) and the basilica of Santa Maria del Mar, in El Born, built by the residents of the Ribera neighborhood.

4. Plaça Reial

A square full of life, with palm trees, the Three Graces fountain, lampposts designed by Gaudí and arcaded buildings lined with terraces. Perfect for a drink outdoors.

5. La Rambla and La Boqueria Market

From Plaça Catalunya, La Rambla runs down about 12 blocks to the Columbus monument and the old port. It’s a must-do stroll, but with two tips: watch your belongings and be wary of the “guess which cup” games, which are scams. Halfway down, stop for a bite at La Boqueria Market.

6. Plaça Catalunya

The city’s most famous square and the spot where almost all transport arrives and departs, including the Aerobús. La Rambla starts here, and the big department stores are all around it.

7. Barcelona Cathedral

Beyond the Sagrada Familia, the Gothic cathedral right in the Gothic Quarter is impressive from the outside, with its stone details. There’s an entry fee to go inside.

8. Montjuïc and the Magic Fountain

One of our favorites. The Magic Fountain of Montjuïc is huge, with colored lights, music and impressive water jets, and the show is free. It gets crowded, so arrive a little early to get a good spot.

In October 2026 it runs Thursday to Saturday from 21:00 to 22:00, and in summer, Wednesday to Sunday from 21:30 to 22:30. Check the official calendar, because it changes with the season.

9. The MNAC (Museu Nacional d’Art de Catalunya)

A huge building that catches your eye from afar and one of the best spots for panoramic photos of Plaça d’Espanya. Entry costs €12 (including the viewpoint terraces) and it’s free on Saturdays from 15:00 and on the first Sunday of every month, with online booking. Combine it with the Magic Fountain at sunset.

10. The Arc de Triomf and Ciutadella Park

The Arc de Triomf is another symbol of the city and the start of a lovely walk to Ciutadella Park, with its boating lake and the Castle of the Three Dragons. A green breather right in the center.

11. Barceloneta Beach

After a day of monuments, Barceloneta is the place to recharge: sand, a seafront promenade and places to eat. We walked it all the way to Port Olímpic and came back by metro from Ciutadella | Vila Olímpica station.

12. The Museu d’Història de Catalunya

On the port promenade, steps from Barceloneta, it walks you through the history of Catalonia. The permanent exhibition costs €6 and is free on the first Sunday of every month.

13. Casa Batlló

One of Gaudí’s most spectacular houses, on Passeig de Gràcia. We only saw it from the outside, but inside it’s highly recommended: the general visit costs from €29 when you buy online (it’s more expensive at the ticket office).

14. La Pedrera (Casa Milà)

A few blocks from the Batlló, “La Pedrera” has shapes taken from nature and a rooftop famous for its chimneys. We didn’t go in either, but today there are daytime visits from €29 and a sunset visit (Sunset) from €25.

15. The Palau de la Música Catalana

A gem of Catalan modernisme. You visit it on a guided tour (€24, about 50 minutes), with tours in Spanish.

16. The Sant Pau Art Nouveau Site

We loved it. It’s like a mini city of modernista architecture, designed by Lluís Domènech i Montaner, and it’s surprising to learn that it was a hospital, a garden city for patients. Today it’s a World Heritage Site, and you can see the Sagrada Familia from the entrance. Self-guided visits cost €18 (€17 from 14:00).

17. The Bunkers del Carmel, the best free viewpoint

For us, the best free viewpoint in Barcelona: a 360° view of the whole city, from the sea to the mountains. They’re the remains of an anti-aircraft battery on Turó de la Rovira, now part of the Barcelona History Museum, and access is free. We got there by bus and walked a few blocks.

Since 2023 the site closes at night (it opens roughly from 9:00 to 19:30 in summer and until 17:30 in winter), so you need to plan your sunset carefully.

18. The Labyrinth Park of Horta

A historic garden with a cypress maze, where we went one day at 15:00 and there was hardly anyone around. We played in pairs… and lost!

Important: the maze is closed for works until early 2027 (they’re renewing the cypresses, the irrigation and the sculptures). The rest of the park is still open: €2.23, and free on Wednesdays and Sundays. It’s easy to reach by metro (L3, Mundet station).

19. Barcelona’s markets

We love markets, and La Boqueria is one of the most famous in Europe. They’re perfect for trying local products and eating something tasty without overspending.

20. Catalan food

Don’t leave without trying pa amb tomàquet (bread with tomato), butifarra and, for dessert, crema catalana. And if you want a specific tip: after a beach day in Barceloneta we ended up at Bacoa, a gourmet burger place we really liked.

Day trips from Barcelona

If you have more days, getting out of the city is well worth it. Our favorites are on the Costa Brava: Lloret de Mar, Tossa de Mar and Cadaqués, which we loved.

How many days to stay in Barcelona (itinerary)

With 3 days you’ll see the essentials; with 4 or 5 you can add Gaudí’s houses on the inside and a day trip.

Getting around Barcelona

Barcelona is very walkable, but for longer distances the metro is fast and comfortable. The T-casual (10 journeys, zone 1) costs €13 in 2026 and a single ticket, €2.90. We found it really useful.

From the airport

• Aerobús: reaches Plaça Catalunya in about 30-35 minutes, with departures every 5 minutes. €7.45 one way and €12.85 return.
• Metro L9 Sud: with the Airport ticket (€5.90). The T-casual isn’t valid at the airport stations.

Where to stay in Barcelona

Ideally, stay close to the metro and the center, so you can get around on foot most of the time.

Tourist tax: since April 2026 you pay the Catalan tax plus a municipal surcharge of €5 per person per night (maximum 7 nights). At a 4-star hotel it’s €8.40 per night and at a tourist apartment, €9.50.

Travel insurance for Barcelona

We never travel without insurance. We use IATI, and through our link you get a 5% discount. If you’re traveling from outside the European Union, check out our travel insurance guide.
