Machu Picchu, Peru
The Place: Machu Picchu, the 15th century Incan citadel sitting atop a mountain ridge, is hands-down the most-visited tourist attraction in Peru — and one of the most photogenic destinations on the planet.
Beat the Crowds: The Inca Trail is logistically fraught. There's a rainy season, lasting from December through April; a dry season, from May through November; and crowds year-round. Our advice: Hire a guide to take you up.
