Parc de la Villette, Paris

This immense site, spread over three kilometers (one-and-a-half miles), is first and foremost a park where both children and parents can play and relax. With its wooded glens, a canal winding through the lawns, staircases climbing up the hillsides to lovely views, and flat lots for roller blading, this place is very popular on sunny Sundays. Children of all ages are invited to unleash their imaginations here: dragon gardens, astounding acrobatics, gentle dunes, and rolling fog set the stage. Linger for awhile in the Bamboo Garden to hear the wind blowing through these enormous grasses and imagine you are surrounded by jungle! Central to the park, the Cite des Sciences et de l'Industrie and the three-dimensional movie theater Geode , which glitters with multi-faceted mirrors.
