The Lost City of the Incas sits dramatically perched on a mountain ridge 2,430 metres above sea level, surrounded by cloud forest and towering peaks. Machu Picchu is one of the New Seven Wonders of the World and the most iconic archaeological site in South America.

Built in the 15th century and abandoned during the Spanish conquest, the citadel remained hidden from the outside world until 1911. The precision of the Inca stonework — cut without mortar yet fitting together perfectly — continues to astound engineers today.

Pro tip: Book the extra ticket for Huayna Picchu (the peak behind the classic photo) months in advance — only 400 people per day are allowed. The sunrise view from the Sun Gate is unforgettable.
