Wild & Scenic Candidate · Grand Teton National Park
The Snake River through Alpine Canyon below Jackson Hole delivers the biggest whitewater in Wyoming — 26 miles of Class III–IV rapids framed by the Teton Range. Grand Teton National Park headwaters feed world-class Yellowstone cutthroat trout fishing alongside genuine big-water excitement. The canyon section from West Table Creek to Sheep Gulch packs eight named rapids into 8 miles.
