Ballon de Paris
Parc André Citroën, 15th
Head to the modern Parc André Citroën and you'll find a moored hot air balloon, which can lift 30 adults (or 60 kids) up above the skyline, offering tremendous views of Paris. This is a prime picnic spot in the summer when the kids can play in the fountains and the modern serial gardens (each is aligned with a different color) are in full bloom. Horticulturists shouldn't miss the two greenhouse pavilions, which are lined with exotic plants.
