Machu Picchu, Peru

Why It’s Amazing: Though many theories exist about Machu Picchu’s purpose (a prison, a resort, an agricultural test site, an aristocratic estate), there’s no denying the cosmic beauty of these methodically carved, fog-covered peaks, engineered by the Incas in the 15th century. To witness dawn spilling over the lush Peruvian Urubamba Valley is an unforgettable experience.
Secret Viewing Spot: Only the first 400 visitors to the site each day are given access to Huayna Picchu, the peak that overlooks Machu Picchu’s ruins and offers spectacular vistas of the surrounding cloud forest.
When to Go: June is a quiet month; on Sundays many tourists head to the nearby Pisac Market instead.
