Where do I do my business on Kilimanjaro and how do I keep myself clean?

The topic nobody wants to talk about, but everybody wants to know about.

Are there showers on Kilimanjaro?

Warm water bowls are provided at every campsite on Mt. Kilimanjaro

This might sound a little scary, but there are no showers on Kilimanjaro.

All water on the mountain is carried from the closest stream to the camp and is mostly used for consumption.

To freshen up our cook provides a small bowl of boiled water to wash your hands and face at every campsite in the morning, at lunch and in the evening.
