Restoration Afoot for Ancient Inca TrailsPublication: National Geographic News Date: August 17, 2004 View Article
Each day up to 2,000 tourists flood the ancient Inca mountaintop city of Machu Picchu in southern Peru. They come to marvel at temples built from perfectly chiseled blocks of granite and pay homage to the sun.
Most of the tourists travel by train from nearby Cusco. Others ride the bus. A few hundred heartier souls arrive on foot after a four-day slog along the famed Inca Trail.
