The brooding mountain that towers over the Machu Picchu citadel is a well-known image, but few have climbed the steep rocky path to the top to catch the extraordinary view of the citadel. A well-marked path sets out from the northwest- ern-most edge of the citadel. At that point, hikers will come across a guardpost at which a park warden will request personal information such as full name, passport or ID Card number, or lodgings at Cuzco. The trail to the top opens at 7 am, but hikers are advised not to walk up after 1 pm, as they run the risk of having to spend the night outdoors. After the guardpost, the trail climbs a stone outcrop that links Machu Picchu with Huayna Picchu. The route is steep and somewhat risky, with long stone staircases and dizzying gorges, making the ascent inadvisable for all but those in the best physical condition. The path to the top takes from 30 minutes to two hours to complete, depending on individual experience. Near the top, a guardtow- er and terraces are located in unimaginable spots.
