In the autumn of 1988, Michael Palin set out from the Reform Club with an ambitious plan: to circumnavigate the world, following the route taken by Jules Verne's fictional hero Phileas Fogg 115 years earlier. The rules were simple. He had to make the journey in 80 days using only forms of transport that would have been available to Fogg.

In his most challenging journey to date, Palin tackles the Himalayas, the greatest mountain range on earth. It is a virtually unbroken wall of rock stretching 1,800 miles from the borders of Afghanistan to south-west China. Penetrated but never conquered, it remains the world's most majestic natural barrier, a magnificent wilderness that shapes the history and politics of Asia to this day.

Michael Palin journeys to a vast country of unimaginable contrasts - Brazil. An economic powerhouse, it is host to a staggering variety of peoples. He starts his journey in the north, in the remote mountains and forests on the border with Venezuela, and finishes in the south at the legendary Iguaçu Falls. He travels by river-boat, float-plane and foot to visit tribes deep in the jungle, samples life in the agricultural and mining heartland of Brazil, experiences the modernism of Brasília and the heady mix of Rio de Janeiro, and ventures into the favelas.

In his joyful book, Billy explores this philosophy and how it has shaped him, and he shares hilarious new stories from his lifetime on the road. From riding his trike down America's famous Route 66, building an igloo on an iceberg in the Arctic, playing elephant polo (badly) in Nepal and crashing his motorbike (more than once), to eating witchetty grubs in Australia, being serenaded by a penguin in New Zealand, and swapping secrets in a traditional Sweat Lodge ritual in Canada, Rambling Man is a truly global adventure with the greatest possible travel companion.

Bill Bryson is the world's funniest travel writer, and a master of comic observation.
