Enjoying Barcelona with kids doesn't have to cost money. The city has parks with one-of-a-kind play areas, municipal play spaces and libraries with children's rooms that charge no entry. In this guide we've picked five that work for different ages and are spread across the city: Ciutat Vella, Sant Andreu, Sant Martí and Sants-Montjuïc.
A trick that works: combine two plans in one outing. La Ludo is inside Parc de la Ciutadella, so you can spend the morning in the play space with the little ones and then walk on to the Cascada fountain. Go early, because La Ludo closes at 13:30. And save the Gabriel García Márquez library for rainy or very hot days: it's indoors and air-conditioned.
Mother to mother: at the parks, early morning and late afternoon are the quietest times, especially on the Can Batlló slides. And if you want more ideas, BabaMap's map has over 350 free places with photos, opening hours and comments from other families.
