In the Sixties, hundreds of thousands of young Westerners blazed the hippie trail from Istanbul to Kathmandu.
Aboard the weirdest procession of unroadworthy vehicles ever to rattle across the face of the Earth, they reached for a new kind of life.Rory Maclean retraces their wide-eyed adventures along a route reopened for the first time in a generation.
Rory Maclean meets one of the original Flower Children making a nostalgic return visit to Turkey.
But the country she knew has changed almost beyond recognition and this generation's backpackers have little in common with the original Intrepids.
Rory reaches Afghanistan.
But the days of dope smoking Londoners in stinking fur coats is a distant memory, as today's Western visitors search for oil or remain holed up at Bagram air base, separated by wire fencing from the country that so enchanted the Flower Power Generation.
As he retraces the hippie trail, Rory leaves the Turkish and Persian empires behind him and crosses the border into Pakistan.
Rory has reached Rishikesh, the mother of pop ashrams - where the Maharishi Mahesh Yogi played host to The Beatles at his Academy for Transcendental Meditation.
But Rory is not just interested in the effect that Rishikesh had on the young Westerners who visited it in the '60s, but the effect that they on it and the legacy they left behind.
