Tibet is one of the world's most extraordinary destinations and there is adventure indeed hidden around almost each and every corner. Lhasa, the capital lies high in the arid wilderness of the Tibetan Mountains, its name "the Roof of the World" is no idle statement. The valley bottoms of Tibet are higher than the highest mountains elsewhere. It's snow covered plateaus are the highest in the world and apart from Everest, which Tibetans see from 'the other side', many mountains are over 15000 feet. Lhasa, at (3590 meters), is Tibet's religious, cultural and economic centre. The 1000 room Potala Palace physically dominates Lhasa City.
