This was one of the most uncomfortable aspects on our mind. Been out in the open hundreds of times and it’s inevitable when you travel a lot, or take long road trips. But we always carry water and that’s good. However, we were told we need to use toilet paper on the trek and water would not be available. I’ve used toilet paper a few times in the past and I was not happy about it. 🙁
The truth is- our trek was along the water stream all through. Now it makes sense, and it didn’t occur before the trek to us, but we do need water to drink, to cook and to wash the dishes/ plates etc. Carrying that much water is practically insane. So, all our camping sites will of course be near a stream. I can’t express how comfortable it made me feel when we realized we had water! 😀
Our trekking company pitched ‘toilet tents’ at every camp site. So, in plain terms, a small tent for privacy, inside which, a deep hole is dug. Every time anyone uses the ‘toilet’, you ‘flush’ it (or cover it up) with the loose mud available from digging the hole and it’s ready for the next one.
We preferred out in the open. It might mean, sometime or the other, exposing your ass to a big patch of ice :D, but the comfort of having water and not having to use the toilet paper takes higher precedence. Of the two bottles I recommended, 1 is for drinking water and 2 is for this. We also always promptly filled the bottles after use and carried it in the back pack.
