Tibet is probably the only destination among the Himalayas that's not as known for its adventure circuits as the rest are. There's much more to Tibet than Buddhism, monasteries and cold desert-like weather.

Climate & Trekking Season In Tibet
Tibet's high altitude and the atmosphere allow the sun's solar radiation to strike the earth with unusual intensity. To protect your eyes and skin, you'd better to bring the sunscreen, which with a sun protection factor of 15 and sunglasses are also useful. Generally from April to October is the best season for opting a Tibet tour. But it really depends on your route and a normal winter Tibet tour schedule is quite comfortable, because in winter, the tourist rush is not much and you can enjoy the beautiful scenery freely.
