The Amarnath Shrine Board has asked all pilgrims not to drink alcohol or caffeinated drink and to start physical exercise at least one month prior to the pilgrimage which begins 29th of June. In an advisory, the Board said, the pilgrimage to the holy cave involves trekking at altitudes as high as 14 thousand feet. <br/><br/>To avoid high altitude sickness, the Board advised the pilgrims to prepare for physical fitness by starting a preparatory morning and evening walk, about 4 to 5 kilometre per day, at least a month prior to the pilgrimage. It also advised pilgrims to take compulsory rest at various locations and ensure time logging and take ideal walking time mentioned on the display boards while moving towards next location. The pilgrimage will take place from 29th of June to 7th of August.<br/>
