The summer festival season is in full swing, and the Paleo Festival, held outside Geneva in the sleepy town of Nyon, offers an alternative to some of its grubbier European siblings. With the mountains on one side and the lake on the other, a wide selection of international cuisines, and an eclectic musical line-up, this is festival-going Swiss-style. Robert Bound dons his Wellies to see what it's all about.
