Despite the peace and tranquility conjured up by its astounding natural beauty, Machu Picchu is a fervently protected place, inhabited by numerous whistle-blowing guards who noisily herd unsuspecting travelers who have strayed from the main path. To explore the ruins in peace, the best option is to hire a guide or to buy a map and stick to the specified routes. Guides are available on the site, and often prove to be extremely knowledgeable.
From the ticket booth, you'll enter the south side of Machu Picchu through the Guard's Quarters, now the modern-day entrance. From here, there are a number of ways to explore the ruins, all of which offer striking views of intricate Inca architecture, Andean mountains and terraced staircases. A few of the can't-miss Machu Picchu attractions include the Temple of the Sun, Royal Tomb, Three-Windowed Temple, Chamber of the Princess, Principal Temple, Intihuatana, Huayna Picchu, Temple of the Moon and Intipunku.
