The Historic Sanctuary of Machu Picchu, a UNESCO World Heritage site, is a breathtaking Incan citadel set high in the Andes Mountains of Peru. Travelers typically reach Machu Picchu via the town of Aguas Calientes, journeying either by train from Cusco or by hiking the iconic Inca Trail, which requires a permit booked months in advance. Solo exploration is possible, but hiring a guide can enhance your understanding of the site's rich history and significance. It's open year-round, but the dry season (May to September) is ideal for visits. Tickets are limited and should be booked in advance, with costs varying depending on entry plus optional shuttle and guided tour fees. Plan for a full day to fully appreciate the site. While access is straightforward in terms of travel options, acclimatizing to altitude is advised if coming from lower elevations.
