Watch a Kayaker Master the Everest of Whitewater

GoPro athlete Rafa Ortiz and pro kayaker Isaac Levinson strapped their GoPros to their helmets and paddled British Columbia’s Stikine River to show viewers the wildest rapids from 60 miles and three day’s worth of big water kayaking on the legendary river.

The Stikine is considered one of the last truly major wild rivers in the world and is one of the most remote. Referred to as "the Everest of whitewater kayaking," it is characterized by deep gorges still lined with glaciers and fast-flowing waters cutting through the Cassier Mountains. The Grand Canyon of the Stikine has been navigated by less than 50 whitewater kayakers, which truly proves its status as some of the toughest paddling in the world.

In the video, Ortiz and Levinson tear through the class V rapids, with Levinson admitting at one point, “That was the heaviest swim I’ve ever encountered.”

Ortiz paddled on National Geographic's source-to-sea Amazon Express expedition in 2012, and was the first to descend the Alseseca River falls in his home country of Mexico. Levinson was a member of the U.S. Slalom team from 2008 to 2012 and was named 2012 Paddler of the Year by Canoe and Kayak magazine.
