As early as when he was five, Prabhu Ghate appears to have been bitten by the travel bug. By age seven, he had already undertaken five ocean voyages and spent three days on a flying boat. The luxury of being able to travel so widely at such a young age is, of course, a function of the privileged circumstances he grew up in. But admirably for Ghate (who went on to study in the UK, join the IAS and travel to many parts of the developing world in the line of duty), he later pretty much forsakes the accoutrements of privilege and seeks out the rough road, the better to savour the travel experience. By Thumb, Hoof and Wheel is an extraordinary account of his travels over nearly 70 years, to some pretty outlier spots around the world, by hitchhiking, on horseback, by car, by train, by riverboat, by ship&mdashand, when unavoidable, by plane.

Ghate is an artful raconteur with a keen eye for detail and, evidently, a prodigious capacity to recall every microdetail even half a century later. But beyond the travelogue narrative, which is fascinating in itself, what embellishes Ghate&rsquos account is the historical backstory he provides to the places he visits, linking them up with more contemporaneous times.

Many of Ghate&rsquos scintillating itineraries are replicable even today, but a few&mdashsuch as his taking a paddle steamer up the Nile through Sudan, or taking a boat from Mombasa to Mumbai&mdashare no longer possible to do. To have travelled so extensively in an era when security and visa complexities were far fewer must certainly count as a blessing. But as Ghate emphasises repeatedly (and demonstrates through his lived-in experience of travel), to savour the world&rsquos treasures, you don&rsquot have to be rich or young. You just have to be &ldquoyoung at heart, reasonably fit, empathetic and curious.&rdquo

Of course, if like Ghate you are a wanderer at heart and a nomadic soul, yet new worlds will open themselves up to you. By Thumb&hellip is a delightful read, and a celebration of the joy of travel on the cheap.
