Trekking in Tibet has it's own advantage. Travelers will experience the breath taking grandeur and beauty of nature on the Tibet. The best time for trekking is May to July and Sep. to October. August is rainy season. Popular trekking places includes Kailash, Rongbuk in Everest area, Namsto Lake, Ganden and Samye,Eastern Tibet, Kharta etc.

Most trekking is conducted in the center of the country in the vicinity of the major towns and highways. Cities such as Lhasa and Shigatse provide bases from which to equip and lunch treks.

Eastern and much part of central Tibet are laced with large mountain ranges, towering passes and deep valleys and gorges. Western and northern Tibet are even higher, but between the mountains are expansive valleys and plains that can take days to traverse.

Tibet, the largest and highest plateau on the earth, is surrounded by the most extensive jumbles of mountains found on any continent. Stretching for almost 1900 miles (3000km) and forming its entire southern boundary is the Himalaya, and along its western extremity is the equally rugged Karakoram; between these two ranges are all fourteen of the world’s 8000-meters peaks (greater than 26,25o feet in elevation), including the soaring heights of Mount Everest. In Northern Tibet the plateau is a high, arid expanse know as the Jhang Thang, the “ Northern Plains,” where no trees grow and summer temperatures can fall far below freezing. Eastern Tibet is bounded by a succession of mountain, the Hengduan Shan, where three of Asia’s largest rivers cut deep, parallel gorges on their journey from the plateau to the sea. 

Many people in the West think Tibet is like the Jhang Thang- a desolate, cold, windswept desert on the roof of the world- but an unusually diverse and strikingly beautiful landscape of snowcapped summits, lush rhododendron and conifer forests, and fertile agricultural valleys also lies beyond the Himalaya. 

Currently, tourists have the choice of either arranging a private group with an itinerary of their own design or joining a commercially organized trek.  
When to go trekking ?
 In general the best season for trekking is from May through October. The weather during these months is surprisingly mild with warm days and cool to chilly nights in the mountain: not very different from summer conditions in the Rockies or the Cascades. July and August can be very rainy, receiving over half of Tibet’s annual precipitation. India’s monsoon manages to push over the Himalaya into much of central Tibet, bringing rain most nights and occasional  showers during the day. This time of year is also prime wildflowers season, when even the most barren hills don a fuzzy green coating of grass. Higher up in the  alpine areas the valleys become  lush and speckled with innumerable types of flowers and blooming shrubs. 
 By September autumn is knocking on the door. The days are cooler and the willow and poplar leaves acquire a yellowish cast. Indian summers are not uncommon and may last into late October or early November, Bringing sunny days and clear, crisp nights with temperature often dropping below freezing. But September and October can also bring surprise snowstorm to the mountains. 
EQUIPMENT & CLOTHING
If you want to go trekking in Tibet you have to book your trek through a travel/trekking agent who will supply all the necessary camping equipment. Although sleeping bags are also provided some outfits prefer you bring your own personal sleeping bags because the rented ones are not very clean and always have some residual odor from the previous usage.  Tents, kitchen equipment, all other camping gear, support staff, cooks, porters and meals are generally included in the price quoted.  With regard to clothing you must constantly compare an item’s effectiveness against its weight. If  you’re not buying everything new. One alternative is to rent gear. If you plan to enter Tibet from Nepal and return there, it is possible to hire camping equipment and winter clothing such as parkas from trekking shops in Katmandu, particular in the tourist area of Thamel. (Trekking gear is not presently available for rent or sale in Lhasa.) Another way to save money is to purchase used gear or buy” seconds” from factory outlets. Local newspapers and bulletin board at grocery stores or outdoor stores are good places to advertise or find ads for used equipment. 

When planning your clothing needs for a trek, think in terms of layers. Layers of clothing will keep you warm, but can be removed to gradually prevent overheating. During spring and autumn the night temperatures in the mountains often dip below freezing, making warm gear essential. In summer the days can be hot, requiring light cotton clothing. Adequate wet-weather gear is also a priority during the summer. Remember that the mountainous regions of Tibet can receive snow any month of the year, and always be prepared for cold weather if you will be trekking at elevations much above 16,000 feet (4880m). Make sure that the clothing you will wear most often can be washed in cold stream water and dries quickly
