• Rowing boats on the lake that kids can paddle around the central pond, best in the morning
• A life-size stone mammoth to climb beside the water, the park's favorite photo stop
• Several playgrounds inside the park, with Barcelona Zoo filling the southern half for an easy combined day

Parc de la Ciutadella covers 17 hectares of flat, shaded paths around a rowing-boat lake. Kids can climb the life-size stone mammoth, explore the monumental Cascada fountain (a young Gaudí helped design it), and visit the Castell dels Tres Dragons. Several playgrounds are dotted through the grounds, and Barcelona Zoo occupies the southern half. Open daily, 7am to dusk.
