You can’t do Barcelona without doing Gaudi. If you’re staying in Eixample near Diagonal and Passeig de Gràcia (try Hotel Omm) you’ll be able to wave hello to two of his most popular landmarks in the city centre, Casa Milà and Casa Batlló, on your morning coffee walk (Satan’s Coffee Corner is a pleasant 20-minute walk away). To delve deeper, join Barcelona Architecture Walks for a tour with a knowledgeable architect who will tell you everything you need to know and more about Gaudi’s famous and lesser-known works across the city.
You’ll learn all about Sagrada Família but to see it up close you’ll need to go by yourself later, as it is a bit farther away from the other sights, as is Park Güell. Barcelona Architecture Walks also runs themed tours around urbanism, the port, current architectural hotspots and an intriguing tour called “Barcelona & The Future”. They ensure their walks are wheelchair accessible and children under 12 are free. You can have a private tour, but need to book ahead.
