If you want to know how treacherous the Yellowstone River can be you might want to watch this incredible video from Red Bull. Professional kite surfer Kai Lenny from Hawaii somehow not only kite surfs the Yellowstone River but does it upstream which sounds insane.

The video shows just how incredible the rapids are in the river and they aren't just for recreational use. I would also check out this interview with Red Bull because he talks about how he almost hit a power line, saw some grizzly bears and loved coming to Yellowstone National Park.

Check out that interview at Red Bull.
