After breakfast in our campsite in the verdant Pacamayo Valley we start ascending towards the small but impressively set ruins at Runkuraqay and on to Cochapata set just below the second pass at 3,900m (12,800ft). From here we walk the short distance to the pass and then descend past a mysterious small green lake to the large ruins of Sayacmarca and on to the last pass at 3,800m (12,450ft) which is more like a low ridge-line than a true pass. From here we get a great view down into the forested gorge of the Urubamba River set more than 1700 metres below us. A short hike from here takes us to our stunning final campsite set above the site of Phuyupatamarca 3,600m (11,900ft), so aptly named the ‘City in the Clouds’. This wonderful campsite – perhaps the most beautiful on the entire trail – is used by very few groups since the vast majority continue for another 90 minutes to camp at the often extremely crowded site at Wiñay Wayna. Below us are laid out the great forest-covered peaks and deep dark valleys - the setting of our goal, Machu Picchu.
