As per the lore, Mata Vaishnodevi took abode in the the Ardh Kuwari cave for 9 months before heading to the main Bhavan. In the modern day, pilgrims have been using this cave as a stopover before continuing their journey upwards to the Bhavan.
Kids seem to love the adventure that this cave is. Pilgrims are required to crawl on their knees to cross the cave. The other side is home to a shrine dedicated to the three Goddesses – Kali, Laxmi and Saraswati. After your darshans, you exit from the other side due to the semicircular route. The exit is at a small distance from the entrance.
