To tourists from outside of Tibet, travel to Tibet is a little bit complicated mainly because of the permits and some formalities to go through. Yes, the situation is just like this. Even our local travel agencies some times do not know how many permits a group has to apply if the group is going to some unpopular places, if we do not ask the concerned authorities, especially the routes cover the trans-Tibet areas.
Take the following itinerary for example, some times the group has to apply with Tibet Tourism Bureau, Tibet Autonomous Region Foreign Affairs Office, and Tibet Public Security Bureau. But some times one or two more authorities. So in our suggestion you’d better contact us for the detailed information if your requested itinerary is not popular.
