The importance of Babadham increases during the month of Shrawan. During this period, lakhs of devotees throng the Baba Baidyanath temple. Most of them first visit Sultanganj, which is 105 km from Babadham.
In Sultanganj, the Ganges flows to the North. It is from this place that the devotees collect water in their kanwars and carry the holy Ganges water, with the kanwars on their shoulders. They walk 109 km up to Baba Baidyanath temple at Babadham reciting Bol Bam on the way.
On reaching Babadham, the kanwarias first take a dip in the Shivaganga to purify themselves, and then enter the Baba Baidyanath temple, where the Ganges water is offered to the Jyotirlingam.
This pilgrimage continues during the whole of Shravan for 30 days, during July-August. This is the longest religious fair in the world.
People from foreign lands also visit Babadham not only during Shrawan month but also during the rest of the year.
The sight on the way from Sultanganj to Babadham is of a 109 km long human chain of saffron clad pilgrims. It is estimated that within this period of one month around 50 to 55 lakhs pilgrims visit Babadham.
Besides the great pilgrimage of Shrawan, almost the whole year remains under fair with Shivaratri in March, Basant Panchami in January, Bhadra Purnima in September.
