All non-Chinese passport holders need a Tibet Entry Permit to visit Tibet, and the only way to enter Tibet is to travel in groups. No individual travelers are allowed to travel to Tibet at the moment. All tours must be booked in advance by a Chinese travel agency, like us. Your whole tour in Tibet must be accompanied by a licensed tour guide.The Tibet Entry Permit is very important. It will be checked at the train station/airport, when you enter attractions in Tibet, and even when you check in to a hotel. So take care of it.
