The real ‘lost city of the Incas,’ Vilcabamba – also known as Espíritu Pampa – is what Hiram Bingham was looking for when he stumbled on Machu Picchu. The beleaguered Manco Inca and his followers fled to this jungle ret- reat after being defeated by the Spaniards at Ollantaytambo in 1536. The long, low-altitude trek, which takes four to nine days, is very rugged, with many steep ascents and descents before reaching Vilcabamba, 1000m above sea level. You can start at either Huancacalle or Kiteni.
