Same method as our Tokyo and Paris guides: every spot here comes from real Barcelona trips planned in Routely, and we only kept the ones at least three different travelers saved on their own.
The essentials
Casa Batllo
Saved by 18+ travelersThe most-saved spot in Barcelona, and honestly the one photo that makes people realize Gaudi wasn't just doing a slightly different kind of church. Eighteen separate travelers saved it on their own trips.
Park Guell
Saved by 17+ travelersA public park that happens to look like it was designed for a fairy tale, because it basically was. Book the timed entry for the monumental zone ahead of time, everyone who's been will tell you the same thing.
Casa Mila La Pedrera
Saved by 16+ travelersThe other Gaudi building on Passeig de Gracia, and the one people save when they want the rooftop chimneys without the Casa Batllo crowds. Sixteen travelers went out of their way for it.
Barcelona Cathedral
Saved by 15+ travelersNot the Sagrada Familia, which is what half the people who save this are expecting when they show up. It's the actual cathedral, sitting in the middle of the Gothic Quarter, and it holds its own just fine.
Where to eat and wander
Mercat de la Boqueria
Saved by 17+ travelersThe most-saved food spot in the city, tied with Park Guell for popularity overall. Yes it's on every list, yes it's still worth wandering through slowly instead of speed-walking to the one juice stand you saw online.
Gothic Quarter Barcelona
Saved by 11+ travelersNo single address, just a neighborhood people save as a whole because trying to pin one street in the Gothic Quarter misses the point. You're supposed to get a little lost in it.
Parc de la Ciutadella
Saved by 7+ travelersThe park people save for the same reason Parisians save Luxembourg Gardens: somewhere to sit down that isn't a Gaudi building. Seven travelers apparently needed the break too.
Mercat de Sant Antoni
Saved by 3+ travelersSitting right at our three-traveler floor, and that's exactly why it's here. A neighborhood market with none of Boqueria's crowds, found independently by three different people with no reason to coordinate.
