I used this site https://maavaishnodevi.org to book my yatra parchi. To my surprise, I was treated like a VIP to enter the bhawan, no need to wait in que, no need to buy prashad just by paying Rs.50/- online. As devotees must be aware that one has to take a yatra parchi before starting the Vaishno devi yatra, which is available free of cost from Katra. Then one has to buy prashad for Rs. 31/- or more and wait in a que for 5-12 hours depending on the rush. I booked my yatra parchi online from https://maavaishnodevi.org by paying just Rs.50/- per yatri and I was allowed to enter from the VIP gate, I was provided with prashad worth Rs.31/-
Thats not all, one can book rooms in Jammu, Katra, Ardhkunwari, Bhawan and do lots of other useful activities on this site. I am IMPRESSED! I feel as I am blessed by the godess to visit the holy shrine so smoothly. All the devotees planing their visit to Vaishno devi must visit this site.
