Over 2.52 lakh devotees have so far paid obeisance at the cave shrine, they said.
"A total of 309 pilgrims - 236 men and 73 women - left Bhagwati Nagar base camp here this morning for Pahalgam and Baltal base camps in Kashmir to undertake the pilgrimage to the holy cave, which houses the naturally-formed ice Shiv lingam," the officials said.
They said while 213 pilgrims preferred the shorter 16-km Baltal trek in the Ganderbal district, 96 others would reach Pahalgam in Anantnag district this evening and will have to trek for 42 kms from the base camp to reach the cave shrine tomorrow.
The 40-day yatra began on June 29 and is scheduled to end on August 7, coinciding with the festival of Raksha Bandhan.
During the pilgrimage this year 48 people so far died due to various causes, including a terror attack and a bus accident.
While eight yatris were killed in the terror attack in Anantnag district on July 10, a bus carrying the pilgrims from Jammu to Srinagar rolled down into a gorge near Banihal on the highway resulting in the death of 16 pilgrims on July 16.
Meanwhile, 592 pilgrims, including 151 women and two children, left for Rajouri district to take part in the 11-day ongoing Budha Amarnath yatra which began yesterday, the officials said.
