Recently I visited this place with my friends for treaking and I must say it was an awesome trek.It may take 2.5 to 3 hrs to reach the top. It is bit difficult trek, but you enjoy it all along. The experience of the sunset above the clouds simply mind blowing.
We carried tent and stayed there overnight. If you want to experience the sunset you have plan to stay on top, as it is risky to get down in the dark. On top you wont get anything to eat or drink. You have to carry them.
