The Inca Trail to Machu Picchu (also known as Camino Inca or Camino Inka) is a hiking trail in Peru that terminates at Machu Picchu. It consists of three overlapping trails: Mollepata, Classic, and One Day. Mollepata is the longest of the three routes with the highest mountain pass and intersects with the Classic route before crossing Warmiwañusqa («dead woman»). Located in the Andes mountain range, the trail passes through several types of Andean environments including cloud forests and alpine tundra. Settlements, tunnels, and many Incan ruins are located along the trail before ending at the terminus at the Sun Gate on Machu Picchu mountain. The two longer routes require an ascent beyond 4,200 meters (13,800 ft) above sea level, which can result in altitude sickness.
