The importance of this religious spot increases automatically when we talk about the month of 'SRAWAN'.

The north directional flow of GANGA is about 105 K.M. from Baidyanathdham Deoghar and is known as Sultanganj, from where people carry the pious Ganga water and come upto Deoghar on foot and then worship Lord Shiva. This pilgrimage continues during the whole of Sravan for 30 days. Hence this religious fair is considered as being the longest fair of the world. People from foreign lands also visit here. The Sravan fair remains so crowded that is seems one human chain of 105 K.M. All the pilgrims wear saffron colour dresses. They recite 'Bol-Bum' incessantly.

Here almost all the types of untouchability vanish. One general survey speaks that within one month almost 52 to 56 lacs of people visit.

According to one myth, this Kanwariya (Pilgrimage) convention was started in 'Trenta Period'.

Besides the great pilgrimage of SRAWAN almost the whole year remains under fair with SHIVRATRI (March), Basant Panchami (January), Bhadra Purnima (September).

There is a very old burning GHAT (spot) in north (walking distance). This ghat has remained the great centre of TANTRA, VAGRAYANI SARA, MANTRAYANI SHAKHA (Branch), NATH community of Shaivitte remained main Hindu cult of Deoghar during early phase.
