drinking water in South America?

We are traveling to the Galapagos and Macchu Picchu in December. I had a kidney stone and I'm supposed to drink A LOT of water. I don't want to carry or buy bottled water. Does anyone have suggestions for things(filters, treatments?) that will treat tap water so I can drink it and not get sick?

  • Hi there! I researched water filters before my trip to Egypt, and settled on the MSR Guardian. You can research for yourself and see if this purifier will work for you. You will need a 1 liter Nalgene-type CLEAR bottle to screw onto the unit to perform a field test. The bottle is not included. Good luck! Linda B
