What About Refilling a 1-Liter Canteen?
Refill planning affects how useful a 1L container is. Know where reliable water sources exist, plan your refill points, and understand that water availability changes the usefulness of a 1L container.
Never assume a natural water source is automatically safe. When planning a hike around a natural water source, check current guidance from the relevant land-management authority rather than assuming every source is safe to drink. See the CDC, National Park Service Ten Essentials, Leave No Trace principles, and USDA Forest Service.
