Squat Toilets Are the Norm
Like I mentioned before, a lot of the toilets on the trail are just holes in the ground. You definitely work your legs and core by squatting so much, and you do figure out a way to keep your pants (mostly) clean, but it's an adjustment in the beginning.
One important note? Don't have your sunglasses on while using squat toilets. I lost a good pair that way by hanging them on my shirt (RIP to the ones in the photo that fell right off).
