There is no strict deadline for booking your Machu Picchu entrance ticket. However, if you want to fully explore the site, we strongly recommend booking in advance. If you choose Circuit 2, you will see the most.
Circuit 2 Machu Picchu allows you to explore most of the Inca citadel and offers the most complete experience. Availability is limited, and tickets can sell out quickly. To secure your spot on Circuit 2, we recommend booking 6 to 10 months in advance. Once the booking system opens availability for the entire year, travel agencies, Inca Trail tour operators, and travelers immediately start reserving spots, so tickets sell out quickly.
The second most popular option is Circuit 3 Machu Picchu. This circuit allows you to explore the lower part of Machu Picchu. You can also add Huayna Picchu Mountain, Huchuy Picchu, or the Great Cavern. Similar to Circuit 2, tickets for these options sell out quickly throughout the year.
For most of the year, Circuit 1 Machu Picchu usually has better availability. This circuit offers a panoramic view from the Guardian House area, but it does not include a full exploration of the citadel. Although Circuit 1 is available daily, it can sell out quickly during the high tourist season.
