Trek to the beautiful Dzukuo Valley. You will never forget it your entire life. Its a valley at the top of the mountains. What is amazing is that you will find Rivers and waterfalls in this valley which is situated at the top of the mountains. You need to carry your own fooding and lodgings for your stay there. Make sure you carry very warm clothings for your stay there as this place is really very cold. If you start at 6AM you will be reaching the valley around 4PM if you are a really good trekker.
