Machu Picchu is the top attraction in Peru and, in 2007, was voted one of the New Seven Wonders of the World. More than 1.5 million tourists visit Machu Picchu each year, and for good reason. It’s an archaeological gem and one of the finest examples of Inca architecture, stonework and planning. Adding to that is the citadel’s breath-taking location atop a lush mountain ridge, between the two peaks of Machu Picchu Mountain and Huayna Picchu, with the steep sides of the mountain plunging down into the misty river valleys below.

The most famous route to Machu Picchu is the classic Inca Trail, a four-day trek through the mountains, cloud forest and alpine tundra. Alternative treks have become increasingly popular over the last decade or so, and trails like Lares and Salkantay offer different experiences, both geographically and culturally, to the classic trail. Or you can take the train to Aguas Calientes, the lively town below Machu Picchu, and from there a short bus ride up a zigzagging road to the Inca citadel.
