Water slides don't have to involve long lines, crying kids, and suspiciously warm water. There are plenty of natural water slides scattered throughout the country that offer relaxation and exhilaration, not to mention a view and a campsite.
Meadow Run (Ohiopyle State Park, PA)
This slide is colossal: a long, fast chute that twists and drops through slabs of bedrock where Meadow Run dumps into the Youghiogheny River in the rolling Laurel Highlands (only a few miles from Frank Lloyd Wright's masterpiece Fallingwater). The stream gets pushy after heavy rains, making for a freakishly fast ride, but even on an average day the flume will hustle you 200 feet or so, in a spray of whitewater, into one of many shallow pools.
