Peru has been home to many civilisations, most notably the Incas, whose ancient cities and fortresses are still being discovered across this fascinating region. This three-part itinerary includes the Inca Trail (or alternative Moonstone Trek), which takes in beautiful mountains and cloud forest as it follows a historic route to Machu Picchu, the best-preserved and most dramatic Inca ruin. It also explores the harsh landscapes of the high altiplano and the islands of Lake Titicaca and, in complete contrast, the dense jungles of the Amazon Rainforest.
