🏆 Virgin Hemlock Cathedral — Ancient old-growth hemlock and hardwood forest in a Cumberland Plateau gorge
Coldiz Cove State Natural Area protects one of the most magnificent old-growth forests in the southeastern United States. The cove’s steep sandstone walls shelter a virgin forest of eastern hemlock and mixed hardwoods that have never been logged—trees reaching 150 feet or more, with some hemlocks estimated at 300-500+ years old. The gorge’s sheltered microclimate creates conditions resembling forests found hundreds of miles farther north, with Canadian-zone plants growing alongside southern Appalachian species in a botanical crossroads of extraordinary richness.
A trail descends into the cove, passing massive hemlock trunks, cascading waterfalls, and rock shelters used by prehistoric peoples. The forest floor supports one of the richest wildflower displays in Tennessee, with spring ephemerals carpeting the ground in April.

Frequently Asked Questions
Is the trail difficult?
The trail descends steeply into the cove gorge. The descent is moderate but the return climb is strenuous. Good footwear is essential as the trail can be slippery. The total hike is approximately 2 miles round-trip.
What is a cove forest?
Cove forests develop in sheltered mountain valleys where moisture collects, wind is blocked, and fire cannot reach. The protected conditions produce some of the tallest, oldest trees in the eastern US — tulip poplars exceeding 150 feet. Cove forests support extraordinary biodiversity — more tree species per acre than almost any other North American forest type.
