Travelling for just 90mins by train from Ollantaytambo, you reach the ruins of Machu Picchu. As the river Urubamba enters its narrow gorge between thickly-forested granite hills, there is room only for a single track, which hugs the right bank and passes through hamlets that are no more than a collection of shacks beside the railway. Close to the foot of the mountain on a saddle of which the citadel was built is the bustling village of Machu Picchu dedicated to serving the many visitors with artisan markets, bars and restaurants.
The majestic ruined city, reclaimed from tropical cloud forest, is reached by minibus up a sinuous road, or on foot up a near vertical rocky path. The American explorer Hiram Bingham discovered it in 1911, by which time it was completely buried beneath jungle vegetation. It sits on a ridge spur amid forested peaks and above a roaring river canyon.
You will have a guided tour of the ruins and there is time later to take one of the many trails within the site itself, such as the hike to the vertiginous Inca Bridge, carved into a cliff edge; or wander among the stone buildings and llama-dotted grassy ledges, soaking up the atmosphere.
