Where's Waldo? In Oregon, deep in the Cascades
Some say this cobalt blue lake is so clean, it feels like distilled water, but that isn't quite true. In fact, it is seven times more pure--perhaps the most pristine lake in the United States, fed almost entirely by snowmelt from the Cascade Range. The drive is about three hours from Portland, Oregon. Make a stop at the Brewers Union Local 180 pub in Oakridge for a burger and an IPA fresh from the cask. Then follow the signs to the Pacific Crest Trail. Hike the stunning path to the shores of the lake and dive in while you can. That's the catch: Come October, the lake disappears under a blanket of ice.
