The Road to Angkor describes a journey through Indo-China from the ancient capital of Champa (now south Vietnam) to Angkor, capital of the old Khmer empire in Cambodia. Christopher Pym originally went to Indo-China in 1956. He stayed 20 months and during 1957 made the seven-week journey described in this book. He travelled the 450 miles on foot, seeking to trace an ancient Khmer road, which may have linked Angkor to the coast.

Overcoming the hazards of tigers, a blocked frontier and the rigours of Asian life at peasant level, and ignoring rumours of wars in Vietnam, he set off into the jungle with a small group of tribesmen. His picture of rural, Buddhist Cambodia, now independent, is of an interesting and little-known country. He describes conditions there and in Vietnam with knowledge and understanding, and gives a fascinating account of the varied customs of tribes found right off the beaten track.
