Trek through Spiti , the hidden trans-Himalayan kingdom known as the Middle Land and a region that has been closed to Westerners since the Sino-Indian War of 1962. You'll cross passes that exceed 17,000 feet and meet people whose culture has been thriving there for over a thousand years. The second, optional portion of the trip takes you to Garhwal, a stunning valley at over 18,000 feet. If you have problems with altitude, this is not the trip for you! Ibex Expeditions, 800-842-8139, September 2000, 28 days, $3,000.
