Huayna Picchu: Huayna Picchu is the mountain that stands next to Machu Picchu. It is a 45-minute hike to the top. Going back down is quite steep if you are scared of heights. You would do this after your tour of Machu Picchu. The cost is $75. Arrangements need to be made at least one month in advance due to popularity. Please understand that the weather is out of our control.
