Train London Barcelona

Explore Barcelona in 2 Days

Arriving at Barcelona Sants station, you step directly into the city’s pulse. The transition from the London to Barcelona train to city street is immediate, and that suits Barcelona. In two days, you won’t see everything. But you can experience enough to understand why people return.

Day One:

Start early with the Sagrada Família. Even before you enter, the sheer scale of Gaudí's unfinished basilica is overwhelming. If you go inside (and you should), let your gaze travel the full height of the nave. Morning is best, as it’s less crowded and more luminous. 

From there, head through the Eixample. This gridlike district is anything but boring. The architecture bends and bulges. Even balconies here are expressive. Between sights, stop for breakfast. A toasted slice of pa amb tomàquet, olive oil gleaming on tomato pulp, with a café amb llet to chase it.

Walk or take the metro toward the Gothic Quarter. On your way, you’ll likely cross Plaça de Catalunya, a busy node where locals wait for buses. Step into the narrow lanes beyond. Here, history lingers in the walls. Visit the Barcelona Cathedral or simply watch the way sunlight threads through alleys. A detour to Santa Caterina Market gives you a less-touristed alternative to Boqueria. Eat standing up: try jamón, manchego and a glass of cava. 

After lunch, head east through El Born. Pass the Santa Maria del Mar, solid and solemn. Shops here sell ceramics and linen. Wander until the air sharpens. That’s when you know you’re nearing the beach. Barceloneta isn’t manicured, but it’s alive: you’ll find kids digging trenches in the sand and plenty of friends relaxing over drinks. 

As evening comes, make your way to Gràcia. Once a village, it still feels detached. Its plazas fill slowly with people. Find a seat outdoors and order vermut. Maybe a few anchovies, a small plate of padrón peppers. Here, meals stretch out.

Day Two:

Begin with height. Take the funicular to Montjuïc. From the top, the city lays open beneath you. The port, the towers, the distant hum of scooters. Visit the Joan Miró Foundation if you have time. If not, just walk through the gardens. They’re quiet, even on weekends and a good spot to slow your pace. 

Make your way downhill to Poble-sec. The streets here are narrower and shaded. Look for a local bar with a menú del día. Don’t overthink the choice. The point is to sit among locals and take part in a rhythm that isn't curated for tourists. 

After lunch, aim for the Raval. You might pass MACBA, the modern art museum, but even if you skip it, the surrounding square is full of life. Skateboarders use the stone ledges as ramps. Nearby, bookstores and vinyl shops are wedged between falafel counters and vintage clothing stores.

If you have time, walk to Parc de la Ciutadella. It’s not Barcelona’s most famous park, but it has space and shade and a lake with rowboats. If it’s hot, you’ll hear cicadas. Sit for a while. Watch the couples, the dogs and you'll even see street musicians. 

Before returning to Sants for your evening, find a quiet café, something local. Order crema catalana if it’s on the menu. It’s a soft, citrusy cousin to crème brûlée.

When to Visit: Choosing Your Season

Barcelona wears its seasons lightly, but they do matter. For train travellers, spring and early autumn are the best times to arrive. Late March through May offers mild temperatures and a city in bloom. Orange blossoms appear in the courtyards. Locals return to their terraces. Parks like Parc de la Ciutadella feel open and lived in, not packed. 

September and October bring quieter streets after summer's peak. The sea is still warm from months of sun, and the festivals—La Mercè in late September, for instance—feel more local than staged. You can walk comfortably all day. Café tables stay full without the jostle. 

Summer, while tempting, comes with heat and crowds. The narrow Gothic Quarter traps warm air. Beaches fill early. Hotel prices climb. If you must visit in July or August, go early in the day and retreat to the museums or long lunches indoors. 

Winter is Barcelona’s quietest season. It rarely freezes. The sky stays blue more often than not. For some, it’s perfect: fewer tourists, better rates, a chance to see the city without a lens of holiday. Still, some places reduce hours. Others close altogether for holidays. 

For a balance of weather, atmosphere, and ease, spring or autumn offers the best experience, especially for those arriving by train from London to Barcelona, already tuned to slower movement and open observation.
