Known as the 'Roof of the World', Tibet lies on an average of 4,000 metres above sea level in the southwest of China. For centuries this mysterious Buddhist kingdom, locked away in the Himalayan Mountains, has exercised a unique hold on the imagination of the West. Today, Tibetan pilgrims across the country can be seen chanting mantras and swinging prayer wheels in temples that are heavy with the thick intoxicating aroma of juniper incense and yak butter. Home of the world's highest peak, Mount Everest and the world's lowest valley, the Grand Yarlun-tzanpo River Valley, Tibet has stunning mountain landscapes coupled with a unique culture making it an incredibly attractive destination.
