Coldiz Cove State Natural Area
🏆🏆🏆 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.

Insider Tips
Gulf cove forest: Coldiz Cove preserves a remarkable “cove” forest in a deep Cumberland Plateau gorge — protected from wind and fire, the cove supports massive trees and lush fern gardens. Pro tip: Cove forests are the Appalachian equivalent of old-growth rainforest — high moisture, rich soil, and giant tulip poplars create a cathedral-like canopy. Waterfall: A seasonal waterfall drops over the sandstone rim into the cove.
Best Time to Visit
Spring: Wildflowers and waterfall at peak flow. Summer: Lush green canopy and cool gorge temperatures. Fall: Spectacular foliage in the cove. Winter: Frozen waterfall in cold spells.
Frequently Asked Questions
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.
