Located high in Peru's Andes Mountains is Machu Picchu, the Inca Empire's most recognised and mysterious ruins. Originally built in the 15th century and later abandoned, Machu Picchu's architecture is highly advanced, well planned, and stretches five miles. The UNESCO World Heritage Site features buildings with panoramic views, 3,000 steps connecting different terraces, and a sunset that cannot be beat. Plan ahead before visiting this site, as only 400 visitors are allowed on the grounds per day. Either hike the famed Inca Trail, a four day trek, or hop on the train and enjoy a scenic ride through the Sacred Valley where you can then head up from Aguas Calientes. Either way, Machu Picchu is an unforgettable experience for any traveller.
