After an arduous trek to the top drains all your energy, the initial views of the valley are all you need to get going again.

The only rest house at the top, to serve as your place of stay for the night. You can start seeing this a few kilometres before you actually reach it and from here on, the trail is either flat or slightly downhill.
Be sure to stay overnight and spend time exploring the valley, else you might miss some of the stunning views from inside the valley.
Settle down with some hot food, listening to your favourite songs, and watch the magic of earth rotating faster than it normally does.
