There are several locations along the route that have outhouse-style toilets that are serviced by trail maintenance personnel. However, trekkers often prefer portable toilets that most tour operators bring on the trek and set up during breakfast, lunch and dinner. They also stay accessible throughout the evening. During the daily trekking segments, there are also places in nature where you will be able to relieve yourself and you may use a urine funnel, if you wish. It is important to note that you are required to carry all solid waste out, because human waste is not permitted to be left along the Inca Trail or its surroundings.
