They tell you to bring backup water purification for a reason! I had iodine tablets that came in handy once the pipeline broke, but some people ignored the messages and were stuck without a filter or purification. Do your diligence when planning your trek. It's a great spot to camp, right next to the creek. Toilets are clean. Some campsites had some shade, others were pretty wide-open for sun. There are 11 sites total so it stayed pretty quiet. Did South Kaibab trailhead to Cottonwood Day 1, up to North Rim and back Day 2, and Cottonwood to Bright Angel trailhead Day 3, which was perfect for our pace.
