“Tumwater Canyon is among some of the biggest roadside whitewater sections anywhere. Located just out of Leavenworth, Washington, the Wenatchee River carves a 6000 foot deep gorge though solid granite. Class V and Class V+ is just steps from the guardrail. We followed 23 year old Sam Grafton as he lapped this big water section all by himself. Despite the guardrail approach and a state full of world class boaters, Sam could not get paddling partners for this section. As of this date, Sam has ran Tumwater’s big water 37 times this year, mostly solo. Subscribe to our Youtube channel to keep up with our latest adventure videos.
