Firstly, the trip cost is excluding the flight fare (I travelled from Chennai) and bus fare from Delhi. I took an overnight bus from Delhi to Bhuntar. The next morning I took a bus from Bhuntar to Barsheni. The govt. bus is cheap travel option and it is on time. After getting breakfast at Barsheni (which is the last stop) you can start on your journey to Kheerganga. It is a straight route and you will meet many fellow hikers on the way up.
