Must-see places you can't miss when you visit Barcelona
1. Sagrada Familia - a beautiful and unique church designed by Antoni Gaudí.
When you think about Barcelona, the first thing that comes to mind is the Sagrada Familia. Undoubtedly, this building is popular and recognized worldwide and represents a great identifying icon of the city of Barcelona.
Construction of the building was overseen by the Catalan architect Antoni Gaudí and represents the greatest exponent of Catalan modernism, although it also pays homage to the Gothic and Byzantine cathedrals.
It has been under construction since 1882 and the date of completion of the work is not certain. This is because it’s considered an expiatory temple, a house of prayer to atone for your sins, and it is being built from donations.
The exterior of the Sagrada Familia has three facades that represent the phases of Jesus’ life: Birth, Passion and Glory. It is the reflection of Christian beliefs that citizenship must follow in accordance with the Catholic religion.
We recommend buying your tickets in advance, as during high season the Sagrada Familia often sells out daily. A great option is the Sagrada Familia: Fast Track + Hop On Hop Off Barcelona Ticket, which combines priority access to Gaudí’s masterpiece with a panoramic bus tour of the city.
In addition, if you’re a religious devotee, you can attend mass in the Sagrada Familia every Sunday. Entrance is free, although the capacity is limited.
2. Las Ramblas, a must-see during your stay in Barcelona
Barcelona’s Las Ramblas is one of the city’s best-known streets as it connects the iconic Plaça Catalunya with the port of Barcelona. It is a very busy road where we can find countless places of interest.
If we start the tour from Plaça Catalunya and walk down the street, we will find the famous Boqueria market. It is one of the city’s oldest markets and in it, we can find a multitude of fresh products such as fruit, meat and fish as well as food stalls where you can enjoy Mediterranean cuisine.
Next, we find the great Teatro del Liceo, a historical and important place where opera lovers can enjoy the best opera shows by artists of great recognition and world fame. Finally, we can admire the majestic statue of Columbus in front of the port.
3. Casa Milà: the building that broke the architectural norms of its time.
If you walk along Passeig de Gràcia, you’ll come across one of Gaudí’s most peculiar works – Casa Milà, better known as La Pedrera. This masterpiece of Catalan modernism is famous for its undulating stone façades and intricate iron balconies. Inside, you can explore a recreated apartment that reflects life in the early 20th century, as well as the spectacular rooftop with its iconic chimney stacks shaped like guardians of the city.
The building was originally commissioned as a private residence for the Milà family, though locals nicknamed it La Pedrera – “the quarry” – because its bold design reminded them of a pile of rough stone. Today, a few private residents still live here, including the well-known writer Ana Viladomiu.
Casa Milà is open daily from 09:00 to 20:30, with shorter hours from November to February (09:00 to 18:30), and also offers special evening visits. Tickets sell out quickly, so it’s best to book in advance. And if you’d like to see more of Gaudí’s iconic creations in the same trip, consider the Park Güell Admission + Sagrada Familia: Fast Track Ticket + Hop-On Hop-Off Bus Barcelona, a convenient combo that lets you explore two of his most famous works while enjoying easy transport around the city.
4. Font Màgica de Montjuïc - one of the most amazing places to visit in Barcelona
Just 10 minutes from Plaza España after crossing its famous Venetian Towers, we find the Montjuïc gardens that house one of the most spectacular fountains in Spain, the Font Màgica de Montjuïc. This is a brilliant place to take your kids in Barcelona.
Designed by the Catalan architect Carles Buigas, it is popular for its light show that, together with the waterfalls, creates a spectacular show that you cannot miss on your visit to Barcelona.
It is an emblematic fountain in the city since many events are held there, such as the final pyrotechnic show of the annual festival of Barcelona, La Mercè.
5. Discover the charms of Barcelona from the Montjuïc Cable Car.
If you like heights, the Montjuïc Cable Car is an unmissable experience in Barcelona. From its cabins you’ll enjoy a unique panoramic view of the city, taking in the harbour, the old town and the Montjuïc hillside. The 750-metre journey is short, but more than enough to see the city from a different and very special perspective.
During the high season it runs from 10:00 to 21:00, giving you the chance to plan your visit at different times of the day – in the morning to appreciate every detail, or at sunset to watch the sun dip behind the city. A practical way to make the most of your visit is to combine access to the cable car with a complete hop-on hop-off bus tour, allowing you to discover the city’s main sights with ease.
6. Enjoy the Mediterranean climate by getting lost in the nooks and crannies of Park Güell.
Another way to appreciate Catalan modernist architecture is by strolling through Park Güell. It has an area of more than 17 hectares and is characterized by its architecture that brings together animal figures, columns with the appearance of trees and geometric figures.
Most of the surface is decorated with colourful mosaics that are peculiarly attractive, and that embody Gaudí’s architectural style. To visit this monumental park, you need a minimum of two hours. However, if you want to visit all the areas, it’ll take much more time due to its large size.
Park Güell is also an ideal place to relax and enjoy the views of Barcelona. We recommend visiting it first thing in the morning or late in the afternoon.
