what's the easiest way .
ha,my friend already went to tibet ,he got it from agency but not travel with group i think
this is why i will never go there.
Informations are highly contradictive. However, it seems that the main reason of this permit is to make money. I heard from several people that they had no problem to run away from an imaginary group.
The other thing that i have heard from several travellers who went by bike that it is legal to enter without permit from any road without checkpoint. Then you can get the permit on arrival in Lhasa or any other major city.
