Who wouldn't want a taste of this magnificent waterfall?! We do! (Vernal Falls in Yosemite NP)

Whatever you're doing—backpacking, kayaking, rock climbing or just getting away from it all and camping out in the wilderness—, you'll eventually need to drink surface water.

So you'll have to drink what you can find along the way, and we'll help you make informed decisions so you can safely consume clean, delicious water.
