Machu Picchu regulations require all visitors to follow a pre-determined circuit within the site as a way to prevent overcrowding. The circuit specific entrance tickets are available on a first come, first served basis. At the time of booking, you may select your preferred circuit, subject to availability. If no selection is made, we will book a circuit based on availability at the time of booking. All circuits offer the opportunity to enjoy the beauty, history, and impressive ingenuity of this ancient site. TO NOTE: Travellers completing the Inca trail and 1-day Inca Trail will be assigned Circuit 3 for their guided visit of Machu Picchu, but will also have access to the panoramic viewpoint upon arrival via the Sun Gate.
