From Kathmandu you can start your trip to Tibet. To cross from Nepal to the Autonomous Region of Tibet one should cross a bridge and pass the police forces that exist there and control each person that want to pass through.
For those that do know, you will feel like you are entering in one of the communist countries. In order to get the license to climb the peak from the Chinese Alpinism Federation you need to appeal to a tourism agency from Nepal. They will anyhow ensure you with all the needing things for your trip – they know the best what you need in this place.
The Friendship Highway passes through a village located at 3500 altitude high – the Nyalam one. Here you will get used to the climate and to the surroundings. Walking on the street you could here just people, no cars. That is a good thing for once. The buildings here seems like long forgotten ones and people that actually worked somewhere, seem to be all Chinese, not Tibetans.
In Tibet as a tourist you are not allowed to travel with the local transportation, to hitch-hike or to sleep where you want. You need to have with you a Chinese person as a guide. Therefore, what one can do here is try to climb the Shishapangma peak and feel the wind at 5000 meters altitude. To resist that high you need to be well equipped and very resistant at the weather. Take all the safety measures both for you and your body when wanting to make such a trip. It is not a mere game
