Vaishno Devi
Break your Vaishno Devi trek at the Ardh Kuwari cave midway, where legend says the goddess meditated for nine months inside a narrow rock crevice. Crawling through the tight passage of Garbh Joon cave is considered a purifying experience and is a must-do on the pilgrimage route.
The cave passage is quite narrow — those with claustrophobia should use the alternate bypass path.
