Grundy Forest State Natural Area
๐๐๐๐ Fiery Gizzard Trail Gateway โ Old-growth hemlock gorge with waterfalls, the jewel of South Cumberland
Grundy Forest State Natural Area is the northern gateway to the legendary Fiery Gizzard Trail โ widely considered one of the finest day hikes in the southeastern United States. The natural area itself protects an old-growth hemlock and hardwood forest in a sandstone gorge carved by Fiery Gizzard Creek, with multiple waterfalls cascading over moss-draped ledges into crystal pools. The 2-mile Grundy Forest Day Loop descends into the gorge through cathedral-like hemlock groves to Blue Hole Falls โ a turquoise swimming hole beneath a 30-foot curtain falls.
The larger Fiery Gizzard Trail extends 12.5 miles from Grundy Forest to Foster Falls, traversing some of the most dramatic gorge scenery on the Cumberland Plateau. The trail’s unusual name reportedly comes from a campfire dinner where Davy Crockett burned his turkey gizzard.
