Sweat Heifer Cascades Loop - 13.35 Miles Round-Trip
Great Smoky Mountains National Park's extensive trail network provides innumerable routing options through the backcountry. The Appalachian Trail joins the Dry Sluice Gap, Grassy Branch, and Sweat Heifer trails to form an ecologically varied lollipop loop through high mountains and low hardwood forests.
Visitors will enjoy several forest types with excellent backcountry camping and wildlife viewing opportunities throughout. The following description heads northeast from Newfound Gap on the Appalachian Trail, and travels clockwise on the loop:
The AT rises over Newfound Gap along the North Carolina - Tennessee border on a rocky, rooted path. Note the absence of hardwoods as you progress through this high-elevation pine-oak forest. The trail crests at 1.5 miles and drops to the Sweat Heifer Creek Trail split (1.65 miles : 5,815').
Grades moderate past 2.0 miles and cross 6,000' (2.2 miles) through columns of red spruce and fraser fir to the Boulevard Trail split, the route's highest point (2.65 miles : 6,014').
The Appalachian Trail continues NE to Icewater Spring Backcountry Shelter (2.9 miles : 5,954') and Icewater Spring, which spills from a pipe directly on the trail (2.95 miles : 5,929'). The shelter is large and well built, but its location on the Appalachian Trail and proximity to Newfound Gap mean it's often crowded.
The trail drops steeply and moderates once again past 3.5 miles on exposed ridges to the spur for Charlie's Bunion (3.85 miles : 5,530'). The landscape changes considerably past Charlie's Bunion, opening to thinly treed hillsides of pine, chestnut, oak, and grasses. This nut and berry-rich ecotone is an important food source for bears, and a good place to see deer, turkey, and grey fox.
Enjoy unabated views down open slopes en route to the Dry Sluice Gap Trail split (4.35 miles : 5,385'). The minimally maintained Dry Sluice Gap Trail rises then undulates on high ridges and sparse hillsides to the Grassy Branch Trail junction (5.6 miles : 5,260').
Veer right on the Grassy Branch Trail, which transitions rapidly from oak and chestnut to Northern Hardwood Forest on the descent. Aptly named Grassy Branch Trail is lightly used, and the verdant grasses lining it may overgrow during peak wet periods.
The trail drops quickly down the west side of Richland Mountain beneath American Beech, yellow birch, and maple, joining Carolina silverbell, basswood, dogwood, and magnolia as you progress in a visibly wetter forest to Upper Grassy Branch (6.95 miles : 4,269'). The understory here is contrastingly thick to drier slopes at higher elevations.
Trail conditions improve on the final descent to Kephart Backcountry Shelter at the Sweat Heifer Creek Trail - Kephart Prong Trail junction (8.1 miles : 3,735'). Turn right on the Sweat Heifer Creek Trail, which crosses Kephart Prong at the route's lowest point.
Once over, the Sweat Heifer Creek Trail begins a long, steady climb through luxuriant forests back to its connection with the AT. Footing is markedly better on this more popular trail. Grades moderate briefly at Sweat Heifer Cascades, which slice down a hairpin turn on the trail (9.3 miles : 4,554'). Three tiers fan out across ribbed rock slabs, all visible but difficult to safely access.
Hardwoods are gradually replaced by spruce and fir on the final push to rejoin the Appalachian Trail (11.7 miles : 5,815'). Retrace your steps back to the trailhead at Newfound Gap (13.35 miles (5,054').

- Arrive early to secure parking at Newfound Gap.
- Late spring blooms and early autumn peaks at high elevations make early summer - early fall the best time to hike this route.
- Note ecological variations as you change elevation, and move from the east to west sides of the loop. High, dry slopes on the east side host sparse pine, oak and chestnut forests, while the Sweat Heifer Creek Trail (west side) is considerably wetter and sees much thicker stands of spruce and fir at comparable elevations.
- A gap is a low point in a mountain ridge. At 5,046', Newfound Gap is the lowest pass through the Great Smoky Mountains. The Appalachian Trail crosses over Newfound Gap Road and straddles the state line between North Carolina and Tennessee for most of its 80 miles track through the Park.
- Those with time should consider an excursion to Mt Kephart (6,217') and the Jumpoff (6,133'). Mt Kephart is the ninth highest peak in Great Smoky Mountains National Park. The Jumpoff is located .2 miles past the summit on its northeast shoulder. This appropriately named cliff edge offers one of the best - albeit from one of the most precarious - viewpoints in the Smokies.
