Machu Picchu and Huayna Picchu, Peru
Declared an UNESCO World Heritage site in 1983, Machu Picchu continues to be a popular tourist destination. Situated in the Sacred Valley in the Andes Mountains, the Incan ruins give you the opportunity to hike through the mysterious and ancient city, or even above it if you choose. Only 400 visitors per day are allowed to climb the stone staircase of Huayna Picchu, which rises 1,000 feet above Machu Picchu for amazing views of the city below. The hour-long slippery and steep climb requires you to hold steel cables for support, and often has low-visibility due to fog and mist. A few visitors die on the mountainous paths each year because of improper gear and a lack of water, so show up prepared. The Lost Girls author, Amanda Pressner Keuser, said she has seen travelers trekking around Machu Picchu in stiletto heels. Don’t be those people.
