Rise high in the sky – 150 metres high, to be exact – with the Air de Paris Balloon. The hot-air balloon has been in residence in André Citroën Park since 1999, ferrying over half a million brave souls to dizzying heights. The balloon provides more than a fix for thrill seekers, though: since 2008, it has also been used to indicate air quality, turning green for good air and orange through red for poor. See Paris from above and get clued-in to what you’re breathing.
