radhika The Yatra as such is not difficult, but the long distances will make you tired. Everyday you have to cover almost 15 - 18 kms on average, but one day you have to cover 27kms. But the natural beauty on this route cannot be found anywhere in the world. Indian Army Men will always be there with you throughout the Yatra.
