There is a reason this trail feels so complete, and it is worth knowing before you set out. Near the end of his life, the Buddha himself is said to have named four places that his followers should visit with a devout heart - the four places where the four great events of his life occurred. This trail carries you to three of them.
The first is Lumbini, in what is now Nepal, where he was born - the one site this trail does not reach, though we can extend the journey to it on request. The other three are here, within the compass of these six days. At Sarnath, just outside Varanasi, he preached his first sermon after enlightenment, setting in motion the wheel of dharma - the teaching begins. At Kushinagar, decades later, he lay down between two sal trees and passed into Mahaparinirvana, his final release from the cycle of rebirth - the teaching's end. And at Bodhgaya, beneath the Bodhi Tree, the event that made all the rest possible: the night a wandering prince named Siddhartha sat down, resolved not to rise until he understood, and became the Buddha, the Awakened One.
Notice the order in which this trail takes them. By geography, it runs Sarnath, then Kushinagar, then Bodhgaya - which means you arrive first at the first teaching, then at the final passing, and only at the very end reach the enlightenment itself. It is, quite by the accident of the roads, the perfect order: you save the place of awakening for last, so that the whole trail rises towards it. By the time you sit beneath the Bodhi Tree on Day 5, you have walked the arc of a life that changed the world.
And there is one more thing that makes Bodhgaya unlike anywhere else - the monasteries. Because this is the holiest site in the Buddhist world, nations from across Asia have built their own temples here, Bhutanese and Thai and Japanese and Tibetan, each in its own style, so that a short e-rickshaw ride carries you through the whole of Buddhist Asia in an afternoon, among pilgrims from every corner of the earth gathered in one small Bihar town.
