water filters (2)
This is a question that is asked frequently by visitors to Yosemite National Park and the answer is NO!
Neither the park nor anyone else can guarantee the safety of the water in rivers and creeks.
Either buy your beverages and cart out your trash or simply buy a water filter.
There are many such filtering devices on the market that range in price from $10.00 up. Check them out!
REI has a good selection. I personally use a chemical by McNett called Aqua Mira Part A & B.
Most filters are easy to carry
