I want to make plans to visit Vaishno Devi. The location is in the hills and in North India where I am not from. I believe that the weather sometimes can get very cold in Katra Vaishno Devi due to it being in the hills and there may be time times during the year when pilgrims experience a lot of rock falls from the hills. In order to decide when I should visit I need to know what the weather in Katra Vaishno Devi is like throughout the year. I don't need exact details but brief details like the expected temperatures, rainy season etc. Thank you for your help.
