The Fiery Gizzard Loop is a challenging but incredibly rewarding hike.
Along the way, you'll pass a series of spectacular waterfalls, such as the 60-foot-tall Foster Falls, Sycamore Falls, and more. After hiking a short stem, the route splits into a long loop.
The route, as mapped here, begins by running through the bottom of a narrow canyon before climbing out and returning along the rim of the canyon.
According to some reports, the hike through the bottom of the canyon along Big Fiery Gizzard Creek is extremely rough and technical, requiring some scree field scrambling and negotiating boulder fields. For an easier hike, you can opt to stay on top of the rim of the canyon and hike an out-and-back along the Dog Hole Trail.
