Visitor numbers to Machu Picchu are restricted to 2500 people per day, even less if you want to explore Huaynapicchu or Machu Mountain with only 400 per day. Planning ahead and booking tickets is a complicated process as the official tickets are issued by the Peru Ministry of Culture only. The official website struggles to function, only reservations can be made online, and payment is due within 6 hours, something that cannot be completed on the official website, only locally through registered banks and tourist offices. After 6 hours the reservations are released.

The booking process is easy and professional, they even have an online chat should you have any queries about ordering. Payment can be made online and you will be sent an email to track your order. It takes approximately 30 days to issue, but you will be informed by email along with a link to print your pass/entry - this can also be confirmed by checking your ticket with the official government website.
