Looking down at the 15th-century Inca citadel Machu Picchu, from the precipitous heights of Huayna Picchu. The peak of Huayna Picchu is about 2,720 metres (8,920 ft) above sea level, or about 360 metres (1,180 ft) higher than Machu Picchu. The only access is via approximately 2,100 slippery eroded stair steps from Machu Picchu that were carved into the side of the mountain over 500 years ago.
