Travel questions? See Good to know in the travel guide below.
Barcelona in late March sits in a genuinely pleasant window: 12-18C, lengthening evenings and the city ahead of its summer crowds. For a two-day machine learning conference that means outdoor lunches are realistic and the beachfront is usable without being packed. The Eixample grid puts most conference hotels within a short metro ride of both the historic centre and the technology cluster around 22@ in Poblenou.
Barcelona El Prat (BCN) is 15km south-west, served by the Aerobus to Placa Catalunya in about 35 minutes and by metro line L9 Sud with a connection into the network. High-speed AVE trains reach Sants station from Madrid in around two and a half hours. The city metro is fast and comprehensive; a T-casual multi-journey ticket is the sensible purchase for a conference stay.
Skip the taxi queue — pre-book a fixed-price airport transfer with Welcome Pickups. Exploring beyond the city? compare rental cars on Auto Europe.
Coverage is strong across the city and the metro. Non-EU visitors should arrange a data eSIM in advance, as roaming into Spain from outside the EU carries significant per-megabyte costs. Set up an eSIM with Airalo before you board and you're online the moment you land.
Sagrada Familia. Gaudi's unfinished basilica, where the interior light through the stained glass is the real reason to go rather than the exterior. Entry is strictly by timed ticket and sells out days ahead. Late morning gives the strongest colour on the nave columns. Ninety minutes including the audio guide. Tickets on Tiqets →
Park Guell. A hillside park in Gracia combining Gaudi's mosaic terraces with wide views over the city to the sea. The monumental zone requires a timed ticket; the surrounding woodland is free. March mornings are cool and quiet. Two hours including the uphill approach or the outdoor escalators. Tickets on Tiqets →
Gothic Quarter. The medieval core between Las Ramblas and Via Laietana, a compressed network of alleys around the cathedral and Placa del Rei. It is best approached without a map, though pickpocketing is a real concern in the busiest lanes. Two hours; early evening before dinner is ideal.
Montjuic. The hill south-west of the centre, holding the Joan Miro Foundation, the Olympic ring and the National Art Museum of Catalonia, linked by cable car and funicular. The views back over the port are the best in the city. Half a day; combine the Miro Foundation with the terrace walk. Tickets on Go City →
How do I get from BCN airport to the city centre?
The Aerobus runs from both terminals to Placa Catalunya in roughly 35 minutes. Metro line L9 Sud is cheaper but requires a line change and charges an airport supplement.
What is the weather like in late March?
Mild and increasingly sunny, typically 12-18C with cool evenings. Sea breezes make the waterfront noticeably cooler, so bring a light jacket for after dark.
Is Barcelona safe for conference visitors?
Violent crime is rare, but opportunistic pickpocketing is common on Las Ramblas, the metro and in crowded tourist areas. Keep bags closed and in front of you and avoid leaving phones on cafe tables.
