Great Smoky Mountains National Park

Log in to track your visit to Great Smoky Mountains National Park.

Great Smoky Mountains National Park straddles the border of Tennessee and North Carolina along the crest of the ancient Appalachian Mountains, protecting 522,000 acres of one of the most biologically diverse temperate forests on Earth. Established in 1934 and one of only a handful of national parks with no entrance fee, the park welcomes over 12 million visitors per year — more than any other national park in the country by a wide margin. The "smoke" in the Smokies is actually a natural haze produced by the trees themselves, which emit organic compounds that interact with sunlight and moisture to create the distinctive blue-grey mist that layers across the ridges. The park's elevation ranges from 875 feet in the valleys to 6,643 feet at Clingmans Dome, creating a staggering range of habitats: subtropical hollows full of rhododendron, mixed hardwood forests ablaze with fall color, and spruce-fir forests at the summit that feel more like Canada than the American South. The Appalachian Trail runs for 71 miles through the park along the state line ridge, and the park's 800 miles of total trails range from paved, stroller-accessible nature walks to rugged backcountry routes rarely visited even at peak season. Gatlinburg, Tennessee on the northern boundary and Cherokee, North Carolina on the southern provide full resort-level services and entertainment for every type of traveler.

Hiking is the centerpiece of any Smoky Mountains visit, and the trail network is genuinely vast. Alum Cave Trail (4.4 miles round trip) is one of the park's finest moderate hikes, climbing through old-growth forest past Arch Rock and massive overhanging Alum Cave Bluffs to views of Mt. LeConte. The Chimney Tops Trail (4 miles round trip) — rebuilt after the 2016 wildfire — delivers dramatic rocky summit scrambling. Laurel Falls Trail (2.6 miles round trip) leads to the park's most visited waterfall, a 75-foot two-tiered cascade along a paved trail. For a full-day challenge, the Andrews Bald hike (3.6 miles round trip from Clingmans Dome parking) emerges from spruce-fir forest onto a grassy bald with panoramic views across the ridgelines. Clingmans Dome Road (closed in winter) leads to the park's highest point and an observation tower with 360-degree views. Cades Cove, a wide valley ringed by mountains, is an 11-mile one-way driving loop past historic 19th-century homesteads, grist mills, and churches, with some of the best wildlife viewing in the park — arrive before 9 a.m. Wednesday or Saturday, when the loop is open only to cyclists and walkers. The park hosts the famous synchronous firefly event each June, when Photinus carolinus fireflies flash in coordinated patterns for two weeks — lottery tickets are required to access Elkmont viewing area. Whitewater paddling on the Nantahala and Ocoee Rivers just outside the park rounds out the adventure options.

Great Smoky Mountains is home to over 1,500 black bears — one of the highest densities in the eastern United States. Bears are active throughout the park and commonly spotted along Cades Cove, Roaring Fork Motor Nature Trail, and at higher elevations in spring. White-tailed deer are everywhere, particularly in Cades Cove at dusk. The park harbors over 30 species of salamander, more than in any other place on Earth, earning it the nickname "Salamander Capital of the World." Over 200 species of birds have been recorded; the park is a critical breeding ground for neotropical migratory warblers including the black-throated blue warbler and the Canada warbler. Wild turkeys strut through the open meadows of Cades Cove, and river otters were successfully reintroduced to Little River.

Great Smoky Mountains is one of the few national parks with no vehicle entrance fee — a rarity that contributes to its enormous visitation. Campground reservations are essential in summer and fall and can be made through Recreation.gov up to six months in advance. Elkmont, Cades Cove, and Smokemont are the most popular campgrounds. Backcountry camping requires a permit (obtainable online through the park's reservation system) and must be in designated shelters or campsites. Fall foliage typically peaks in mid-October at lower elevations, and the park is absolutely packed — plan accordingly. The Sugarlands and Oconaluftee Visitor Centers are the main information hubs on the Tennessee and North Carolina sides respectively.

The park's main Tennessee entrance at Sugarlands Visitor Center is just outside Gatlinburg on US-441, 35 miles southeast of Knoxville and about 180 miles from Nashville. McGhee Tyson Airport (TYS) in Knoxville is the nearest major airport. The North Carolina entrance at Oconaluftee is 2 miles north of Cherokee on US-441. US-441 (Newfound Gap Road) crosses the park summit and is the only paved road connecting the two sides — it closes in heavy snow.

Avoid driving Cades Cove Loop on weekends in summer and fall — the 11-mile loop can take 3-plus hours when traffic is backed up. Instead, visit Wednesday or Saturday morning when the road is car-free until 10 a.m. Bear encounters are common; store all food in bear boxes or certified canisters and never approach a bear. Rhododendron blooms mid-June in the mid-elevation zones and early July at higher elevations — one of the most spectacular flower shows in the Appalachians. The park's highest roads (Clingmans Dome Road, Blue Ridge Parkway approaches) may close for ice October through April. Cell service is minimal or absent throughout much of the park interior.
