No single “ancient route”
There was never one official pilgrimage road to the Mahabodhi Temple. Pilgrims came by whichever paths linked their homes to the plains of Magadha, in eastern India, and the paths changed over time. What survives are some written accounts, a handful of inscriptions and the evidence of the landscape. The summary below sticks to what is reasonably well documented and says when it is uncertain.
The setting: a region of roads and rivers
Bodh Gaya lies in the middle Ganges plain, near the Phalgu river and about a dozen kilometres from the city of Gaya. This region was a centre of early Indian states, and people travelled on foot, by cart and by boat along the river systems. Texts connected with early Buddhism describe the Buddha and his monks walking between cities such as Rajgir, Varanasi and others in this region. Later pilgrims followed these links to the places tied to his life, a set often called the four holy places.
Pilgrims from beyond the plains came from the north-west through Gandhara and the Silk Road, from the east and south by coastal and river routes, and later from the Himalayas through mountain passes. The details differ by period and sources do not give a complete map.
Faxian
The Chinese monk Faxian left China around the end of the fourth century and returned in the early fifth, travelling in search of monastic rules and texts. His account describes a journey across Central Asia, through north-western India and down the Ganges plain, and records visits to the main places linked to the Buddha’s life, including Bodh Gaya (which he describes as the place of awakening) and the surrounding area. He notes monasteries, stupas and a landscape he found sparsely populated in places. Details of his route and dates are discussed among scholars, and his account is short.
Xuanzang
Xuanzang, another monk from China, travelled in the seventh century and left a far longer record. He reached the region around 637 CE by traditional dating, stayed for a time at Nalanda, and wrote about the Mahabodhi area, describing the tree, the stone seat, a large temple and a community of monks. His record also includes legends, such as the story of a ruler cutting down the tree, which should be read as reports of what he was told rather than verified history. Among the Chinese pilgrim monks, he is the one whose account historians use most for this period.
The writings of both monks matter because few Indian sources of the same period describe the sites in this kind of detail.
What the journey meant
For these travellers the journey was part of the practice: an act of merit, a search for teachings and relics, and a way of seeing the places named in the texts. Travel was slow and risky. The accounts mention difficult mountains, deserts and robbers, as well as the kindness of hosts. Monasteries along the way often offered lodging. We should avoid imagining a single standardized “pilgrim path”, or assuming that every pilgrim followed the footsteps of the two Chinese monks.
Later, pilgrims from Sri Lanka, Burma, Tibet and other places came as well, and the memory of their visits survives in inscriptions, travel records and tradition. The wider story of the spread of Buddhism shows why the roads mattered: monks, teachers and texts moved along the same routes as merchants.
Travelling there today
Modern visitors usually reach Bodh Gaya via Gaya, which has a railway station and an airport with a limited number of flights, or via Patna or Kolkata with onward road or rail travel. Road transport from Gaya to Bodh Gaya is short, and taxis, auto-rickshaws and shared transport operate, though availability, timetables and fares change. Check current schedules and government travel advice before you plan.
The cooler months, roughly late autumn to early spring, are the main season for pilgrimage, but crowds and prices are higher. The summer is very hot and the monsoon brings heavy rain. Travel can be tiring, delays are common, and long journeys in the heat call for sensible health precautions and advice from a doctor or official health source.
Many visitors combine Bodh Gaya with other places on the wider India pilgrimage circuit, such as Rajgir, Sarnath and Kushinagar. Each has its own practical rules, so plan each leg separately and allow generous time for road and rail delays.
