Machu Picchu is a World Heritage Site, one of the seven new wonders of the world, and one of the most marvelous places on earth. A remnant of the Incan Empire in Peru, it is reachable by bus from Aguas Calientes. It is best to arrive early in the day for three reasons: 1) only a set number of tourists may enter in one day; after that number is reached, you will need to return another day; 2) the earlier you arrive, the more time you can spend exploring the magnificent site; and 3) watching the city gradually appear out of the clouds as the morning fog burns off is an unspeakably awesome spectacle.
Love me, hate me, kill me, anything. Just let me know it.
