Bobfest is a gloriously unserious free outdoor festival where you can compete in mullet contests, flip-flop tosses, and rooster crowing showdowns while DJs and live bands keep the Guinguette Les Nantais jumping all weekend. Come in your worst fancy dress, bring the kids for the dedicated Chapi-Kids tent, and embrace the "sans barrière et en slip" spirit: pure, ridiculous fun in the sun.
