It should be in every one's to do trek list. Its better if you start the trek early morning. If you are a beginner, for sure you will take more than 2 hours to climb. The last point of the hill is heart lake, because of which this hill got famous.
For a group of 10 people with guide it costed 790 rs. From the ticket counter you can take your vehicle 5km more, from where trekking starts. First you will get the view point. Usually people who are not trekking friendly will visit this and go back :)
There after starts the actual trekking. Totally its 2.5 km trek where 1.5 km is inside forest and remaining 1 km is in open slant grassland. Its little difficult one. But once you reach the top, you will forget all the struggle you took to reach.
It is really a worth visit. :)
