GRUNDY FOREST AREA

About Grundy Forest Area & Little Fiery Gizzard Creek

Tucked into the rugged plateau country of southern Tennessee, the Grundy Forest Area is one of those rare places that rewards you before you even reach the water. The moment you step onto the trail, the forest closes in — a cathedral of hemlock, rhododendron, and hardwood that filters the light into something soft and green. Beneath it all, Little Fiery Gizzard Creek cuts through sandstone, carving out swimming holes that feel genuinely wild, genuinely cool, and genuinely worth the effort to reach.

This is an unofficial swimming destination within the South Cumberland State Park system, which means you'll find natural beauty without a crowd of beach umbrellas. Come with the right expectations — and the right footwear — and you'll leave wondering why you don't do this more often.

The Setting: Sandstone, Waterfalls, and Forest

The roughly two-mile Grundy Forest Day Loop is your gateway to the creek's swimming holes, and the trail itself is half the experience. You'll walk past geologically striking sandstone cliffs streaked with iron and lichen, and through forest floors carpeted with ferns and seasonal wildflowers. The remains of a Civilian Conservation Corps camp add a quiet historical texture to the landscape — stone foundations and earthworks that speak to a generation of young men who shaped these woods nearly a century ago. Overhead, the canopy is dense enough to offer real shade even in July, and the sound of moving water is almost constant once you descend toward the creek.

Sycamore Falls anchors one of the most photogenic moments on the loop — a plunge pool fed by falling water, framed by rock walls. Downstream, the creek widens into stretches calm enough to float in.

Swimming in Little Fiery Gizzard Creek

The creek runs clear over sandstone and gravel, the kind of water that looks almost amber in shallow light but turns a deep, glassy green in the pools. Swimming here is an act of full immersion — cold enough in spring to make you gasp, and refreshing enough in July to make you never want to get out. The natural pools vary in depth depending on where you find them and recent rainfall, so conditions change with the season. There are no lifeguards on site, so swim with awareness and bring a buddy. The best conditions arrive from late May through September, when water temperatures are most forgiving and the trails are at their most lush.

Planning Your Visit

Access to the Grundy Forest Area is free. Facilities at the parking area include picnic tables and toilets — basic but sufficient. There is no car camping within the state park units here, but nearby options make an overnight trip easy. The TVA campground at Foster Falls, located on Route 41 between Tracy City and Jasper, offers camping and its own swimming hole beneath the 100-foot Foster Falls — a strong reason to make a full weekend of it. Fall Creek Falls State Park is another camping alternative in the region.

The nearest towns for supplies, food, and lodging are Tracy City and Chattanooga. Tracy City is your closest stop for last-minute provisions, while Chattanooga — roughly an hour's drive — offers the full range of restaurants, gear shops, and accommodations. Plan to arrive early on summer weekends, as the trail and parking area can see steady use when the weather is good.
