Coupe Icare, also known as the Icarus Cup, is an annual festival of free flight held between Saint-Hilaire (on the border of Chartreuse Mountains) and Lumbin (in the valley of Isère in France). The festival typically lasts four days and is held in the early autumn. Coupe Icare is best known for its Concours de déguisements (Masquerade Flight contest), in which paraglider and hang glider pilots fly in costume to compete for prizes.
