Trekking Season In Tibet 
Generally from May to October is the best season for Tibet trekking tours. May and June are good months without much rain or snowfall but some high alpine passes in eastern Tibet may still be closed by heavy snow. July and August are the hottest months of the year but they tend to be rainy and this can make walking messy. September and October are excellent months for trekking but in high areas the nights are cold and early snow is always a possibility. So anyway it really depends on what trekking tours you will take.

Trekking Preparation
You need to prepare for the extremes in weather and terrain before you take a tibet trekking tour. The time of year you choose will dictate the equipment you will need.

1. Clothing and Footwear.
Minimum you need basic warm clothing, including a hat, scarf, gloves, down jacket ( suggest you buy it when you are in Lhasa), long underwear, warm, absorbent socks, all-weather shell and sun hat, as weel as comfortable well-made pants and shirts. Another important asset is a pair of strong, well-fitting hiking boots.

2. Equipment
As most of our trekking tours will be in the remote areas of Tibet and provisions are hard to find. So a tent, sleepingbag, Mattress and backpacking stove are essential. But all of them can be offered by our travel agency, you can choose just take your own sleeping bag and Tent. And other basics includes water containers with a systerm for water purification, a flashlight, pocket knife, and walking stick which is not only as a walking aid, but also for protection against Tibetan dogs.

3. Protection against sunburn
As the sunshine is really strong, you need to take the sunglasses, sunhat and suntan lotion etc. Ladies should take the high SPF sun-cream.

4.Medicine
Take an adequate supply of any prescription medication you use regularly, including inhalers for asthma. Most over-the-counter medicines, such as aspirin and anti-diarhea pills, are available in Lhasa, but are more difficult to obtain outside of urban areas.

High Altitude Sickness

High Altitude Sickness could happen to any guest in high altitude. The effect of HAS usually remains 2 days till the body acclimatizes. Headache, nausea, vomiting and short breath are the common symptoms. To avoid HAS take garlic soup, more water frequently. Diamox tabs are also recommended.

On the trek

Bear in mind that in many places there are not people from whom to ask directions and the trekking trails in Tibet are not marked.Paths regularly divide,merge and peter out,making route-finding inherently difficult.If you are not good at trail blazing,your only alternatives are to go through a travel agency or to employ a local guide.

Health

To maintain your health in such a difficult high-elevation environment you will need to take some special precautions.Tibet is not the place to wander alone-always trek with companions.If anything goes wrong,you will need others to depend on.In case of a real emergency you may need medical insurance,which should be purchased before leaving home.

Sunburn can be the most common trekking health problem.Fortunately it is preventable by wearing loosefitting clothes that cover your arms,legs and neck.Choose a wide-brimmed hat like the ones Tibetans wear.

Subfreezing temperatures mean there is a risk of hypothermia,even during the summer season.Make sure you have the right clothing and an outer shell that will protect against rain,snow and wind.
