The most dangerous tourist destinations

For many, their highlight of a trip to Peru and Machu Picchu in particular is the steep climb up Huayna Picchu, the mountain that overlooks the “Lost City of the Incas.” Though the climb is steep and often dangerous, the views are worth it: The peak is about 2,720 m (8,920 ft) above sea level and 360 m (1,180 ft) higher than Machu Picchu. The Urubamba River that bends around it adds to the scenic quality.
