At some point, usually around the third day, the city is still wonderful but your legs want a different horizon. Barcelona answers that better than almost any large city in Europe. Within forty minutes to an hour by train you can be on a holy mountain with a monastery built into a cliff, in a medieval Jewish quarter, in a beach town with seventeen beaches, or inside Salvador Dali’s head. Here are the five that matter and, at the end, the question that actually decides it: which one, if you only get a single day.
What is actually within reach
Montserrat, about an hour, mountain and monastery.
Girona, thirty eight minutes on the fast train, medieval stone and the Call.
Sitges, about forty minutes, beaches and a white old town.
Figueres, about an hour, the Dali Theatre Museum.
The Costa Brava, an hour and a quarter by bus to Tossa de Mar, coves and cliffs.
Four of the five are train days. Only the Costa Brava rewards a hire car, and that is the one argument for renting one at all while you are here.
Montserrat, the mountain and the monastery
A mountain of surreal rounded pillars rising off the plain like a wall, with an eleventh century Benedictine monastery on its flank. It is the spiritual heart of Catalonia and the home of the Black Madonna, and it is also a walking destination: funiculars and paths lead to viewpoints that reframe the whole visit, and even an hour on foot changes the day.
The route is the R5 train from Placa Espanya, then a choice at the bottom between the rack railway and the cable car. Combined tickets covering both legs are the usual way to buy. The basilica itself is free to enter; seeing the Madonna up close is a separate, inexpensive ticket worth booking ahead. The boys’ choir is famous and does not sing every day, so check the schedule before you build a morning around it.
It is the classic and it deserves the status. Our full Montserrat guide covers the ascent options, the timings and the walks in detail.
Girona, medieval stone and the Call

A stone city on the river Onyar, with the coloured houses that everyone photographs, a cathedral with a dramatic stair, walls you can walk along, and at its heart the Call: one of the best preserved Jewish quarters in Europe.
The history here is substantial rather than decorative. A Jewish community lived and flourished in Girona until the expulsion of 1492, the city was an important centre of Kabbalah and the home of Nachmanides, and the lanes have survived close to intact. The museum in the middle of the quarter tells the story properly. Our guide to Girona’s Jewish quarter goes through what to see and in what order.
Getting there is thirty eight minutes on the high speed line from Barcelona Sants, or around an hour and a half on a cheaper regional service. Book the fast trains early.
Sitges, a sea day with no logistics
Half an hour south: a white old town with a church on a rock above the water, a long palm lined promenade, seventeen beaches and a relaxed Mediterranean mood. Sitges is also one of Spain’s best known LGBTQ destinations, and the atmosphere is open and easy accordingly.
The R2 train from Sants or Passeig de Gracia takes about forty minutes and the last stretch runs along the shoreline. No planning, no reservations, a few euros each way. Morning in the old town, midday on a beach, an afternoon vermouth on the promenade, and that is the entire itinerary.

One thing worth knowing: trains back run late into the evening, so Sitges works as a sunset and dinner trip as well as a beach one. Plenty of people go down at four, swim, eat on the front and come back at eleven, and the lit church above the sand is the reason.
Figueres, Dali, and the Costa Brava
Figueres is an ordinary Catalan town with something extraordinary in the middle of it. Dali rebuilt the old theatre of his home town into a single vast work, and he is buried beneath the floor of it. Giant eggs on the roof, a car it rains inside, a room that is a portrait of Mae West. Two to three hours covers it, entry is around seventeen euros, and a timed ticket booked in advance is essential in season. Because it sits on the same line as Girona, the efficient move is both in one long day.
The Costa Brava is the wild coast north of the city: cliffs, pine woods running down to the water, and coves with a colour that does not look real. Tossa de Mar, with a medieval seaward fortress, has a direct bus from Barcelona Nord in about an hour and a quarter. But this is the one day where a hire car pays for itself, because the coves are strung along the coast and a car turns one into four. In summer, leave early: the small cove car parks fill by mid morning. Our Costa Brava guide covers which coves are worth the drive.
How to choose when you only have one day
One free day and no strong preference: Montserrat. Closest, most dramatic, least like anywhere else.
History and heritage: Girona, and if you are an early riser, add Figueres in the morning.
A beach with zero planning: Sitges. One train, one towel.
Art is why you travel: Figueres, midweek, with the ticket already booked.
Five days or more and a camera: the Costa Brava with a car.
Barcelona is unusual in how much it puts within an hour of itself. The mistake is not picking the wrong one of these, because there is no wrong one. It is trying to fit two into a single day and seeing neither properly.
One more direction is worth a full day. The Penedès wine country sits inland, with the Cava cellars clustered around Sant Sadurní d’Anoia. A Penedès day trip from Barcelona covers the train, the cellars and the town of Vilafranca.
