I am from Bhutan wanted to go for pilgrimages tour to Lhasa ?

It’s possible for you to get it to travel to Tibet from Kathmandu. You should first find a travel agency and then ask the agency to get Tibet Travel permit for you. After that, apply for a Chinese visa based on the Tibet Travel permit.
Afterwards, you need to book a tour to enter Tibet.

ok thank you very much because i still doubt whether we Bhutanese would get visa to enter Tibet or not.So thank you very much for the information we will surely contact you after our discussion and please write me back how long it will take to reach there from Kerung to lhasa

Please whoever has a news of Tibet permit for Bhutanese can drop me.Recently I heard that Chinese has again closed the entry permit for Bhutanese n for one more country so please whoever has a news can update me soon.
