As a professional kayaker, Dane Jackson has found himself paddling in some fairly unique locations over the years. But the one that you'll see in this video has to be amongst the most harrowing. In the clip above, Jackson drops into the Rio Claro river in Brazil and proceeds to take on some extremely narrow canyons. Of course, narrow canyons and fast-moving water mean wild rapids, which there are plenty to be found as well. Not for the inexperienced or easily frightened, this is one wild ride to say the least.
