Given that you’re in the middle of nowhere on a mountain, do not expect luxury when it comes to toilets. In most of the campsites, there are toilet facilities but they are very basic (mostly squat toilets, plus they can get quite dirty as it is used by everyone. A great thing about booking with Alpaca Expeditions is that at every campsite, they would set up a portable private toilet for just guests. I would suggest having a small bottle of air freshener for the toilet tent to help keep it fresh.
