Cuyahoga Valley National Park, Ohio
When people think of Northeastern Ohio, waterfalls are typically not the first things that spring to mind. And while this 65ft-tall waterfall may not be as beloved as LeBron, it remains a popular swimming hole and main attraction of the 16-year-old Cuyahoga Valley National Park. Take it all in by exploring beyond the falls via the 1.5-mile Brandywine Gorge Trail.
Opal Creek Wilderness Area, Oregon
Hike a long but easy four-mile trail through 500-year-old trees and riverside wilderness to wind up amid the 30ft Sawmill Falls, which deposits your sweaty body into a chilly deep-green pool. The solitude of nature makes fighting screaming kids for a towel at your local pool seem like an exercise in sheer stupidity. Which, of course, it is.
