Peru & Machu Picchu
The views are increasingly spectacular. This is Mt. Machu Picchu with the Sun Terraces and Wiñay Wayna ruins in the foreground. Hiram Bingham rediscovered the trail and most of the ruins in 1914. But Wiñay Wayna wasn't found until 1942. Until recently the trail went through the bottom of the Sun Terraces, but an Inca staircase was discovered in the 1980s that leads down to Wiñay Wayna.
