It is extremely difficult to find an accurate map of the plateau that has topographic and toponymic information, so your best option is to invest in a good guidebook with detailed maps. The seven geographic regions of Tibet are structured around cultural, ethnic, and linguistic differences for Tibetans, but political division of autonomous region and prefectures does not take these considerations into account. Each prefecture is divided into administrative counties that are generally reflective of Tibetan customs and desires.
Unfortunately, many Chinese cartographers have used the names of counties and county capitals interchangeably. Tibetan location names are increasingly becoming replaced by Chinese names. Additionally, a lack of standard translations for Tibetan locations and the local variations on pronunciation make it even more difficult for you as an unfamiliar traveler.
The seasons are similar to those in China, but it is colder due to the high altitudes. April to June and September to November are usually the best months for travel, although they tend to be the most popular. July and August tend to be extremely rainy and you will probably have to struggle with flash floods or high rivers, but August especially is a prime season for visiting festivals. Despite the cold temperatures and resulting challenges of travel, winter is not a bad time to go because it is still very sunny and nomads from all over Tibet journey to Lhasa. March is a politically sensitive month so there may be increased restrictions on travel. Regardless of the month, you should still be prepared for dry air and cold temperatures at night. Western Tibet tends to be drier, and the eastern portion follows weather patters similar to those of Southeast Asia.
Consider timing your trip with a festival if you're interested in experiencing the best of Tibetan culture.
Chinese tourists pour into Lhasa during Chinese week long holidays from May 1 to October 1, so you should be prepared to pay higher prices for rooms and be more flexible about room situations.
Although organized tour groups are more expensive, they give you more access to "closed" areas of Tibet. A tour operator will also take care of travel permits and help with flight arrangements. If you have less money and are physically capable traveling as an individual can be just as rewarding. You should still be sure to take note of any travel limitations or you may face expulsion from a closed area.
The Tibetan plateau is the size of Western Europe, so you should plan accordingly. Depending on which gateway city you use to enter Tibet, you may find it easier or more difficult to reach certain areas within Tibet. These routes are only meant as suggestions of possible journeys that you might consider while in Tibet.
