don't build a bridge over troubled waters
The Grand Canyon, the Elwha, Vallecito Creek, Black Canyon of the Gunnison, South Fork of the Salmon, and Bull Lake Creek. All epic Class IV-V whitewater runs that were once thought to be beyond the capabilities of packraft. All runs that have been ticked off in style by paddlers in the Alpacka Whitewater Series packrafts over the last decade.
Packraft pluss paddles.
