Home, sweet home! The Rincons were my early stomping ground when I attended the U of Arizona and I really like the area. Water sources are not abundant, but those that are marked are fairly dependable - when are you planning your trip?

Truth to tell I never treated any of the water I drank in the Rincons and I have consumed several gallons, but that was fifty years ago. Personally, I would just boil, but any bacterial/Giardia filter should work just fine. I would pay attention to weight.

I would start out with plenty of water - it can be a long pull to the first water source, depending upon the trail. In the summer or fall, that could be over a gallon.
