What Great Smoky Mountains National Park Is and Where It Sits

Great Smoky Mountains National Park is a 816,000-acre protected area that straddles the border between Tennessee and North Carolina in the southeastern United States. The park sits along the crest of the Great Smoky Mountains, a subrange of the Appalachian Mountains. The name comes from the natural fog—called "smoke" by early settlers—that often blankets the ridges and valleys.

The park is one of the most visited national parks in the country. Unlike many other national parks, there is no entrance fee to enter Great Smoky Mountains. The park is open year-round, though weather and road conditions vary by season. The main park headquarters and visitor center are located in Gatlinburg, Tennessee, on the north side of the park.

Key Takeaways

  • Great Smoky Mountains National Park sits on the Tennessee-North Carolina border and charges no entrance fee, making it accessible to visitors of all budgets.
  • The park has over 800 miles of trails ranging from short walks to multi-day backpacking routes, so you can choose based on your fitness level and time.
  • Cades Cove and Newfound Gap Road are the two most popular driving routes, each offering different views and access to trailheads.
  • The park is busiest in fall (October) and summer (July–August), and quieter in winter and early spring, which affects parking and trail crowding.
  • You will need a vehicle or shuttle service to reach most trailheads, as the park does not have public transportation between major areas.

How to Get There and Where to Park

Great Smoky Mountains has three main entrances: the north entrance near Gatlinburg, Tennessee; the west entrance near Townsend, Tennessee; and the south entrance near Cherokee, North Carolina. Most visitors arrive by car. There is no public bus or train service to the park itself, though the towns of Gatlinburg and Pigeon Forge (Tennessee) have local shuttle services that run to some trailheads during peak season.

Parking at popular trailheads fills quickly, especially from June through October and on weekends year-round. Cades Cove, one of the most visited areas, often reaches full capacity by mid-morning. If a lot is full, you will see a sign at the entrance. The park does not hold reserved parking spaces. Arrive early or visit on weekdays to increase your chances of finding a spot. Some smaller, less-known trailheads have more available parking.

Once inside the park, there are no gas stations, restaurants, or lodging. The nearest services are in the towns surrounding the park—Gatlinburg and Pigeon Forge to the north, Townsend to the west, and Cherokee to the south. Plan your supplies and fuel before entering.

The Two Main Scenic Drives

Cades Cove is an 11-mile loop road on the Tennessee side that passes through a wide valley surrounded by mountains. The road is paved and one-way during peak season (May through September). You will see historic cabins, churches, and barns from the 1800s. Wildlife is common here—deer, wild turkeys, and occasionally black bears. The loop takes one to two hours to drive without stopping, or three to four hours if you stop at trailheads and historic sites. Bicycles are allowed on the loop road.

Newfound Gap Road is a 31-mile paved highway that runs north to south through the park, connecting Gatlinburg, Tennessee, to Cherokee, North Carolina. The road climbs to Newfound Gap (5,046 feet elevation) and passes through different forest types as it rises. Clingmans Dome, the highest point in the park at 6,643 feet, is accessible via a 7-mile side road off Newfound Gap Road. The drive takes about one hour without stops. Numerous pullouts and short walks are scattered along the route.

Trails for Different Fitness Levels and Time Commitments

The park has over 800 miles of trails. Short walks (under one hour) include Laurel Falls Trail (2.6 miles round trip, paved), Cataract Falls (0.8 miles), and Abrams Falls (5 miles round trip, moderate). These trails are suitable for families with children or visitors with limited mobility.

Half-day hikes (two to four hours) include Alum Cave Trail (5 miles round trip, steep), Chimney Tops Trail (3.4 miles round trip, very steep), and Grotto Falls (2.6 miles round trip). These require a moderate to good fitness level.

Full-day hikes (five or more hours) include Mount LeConte (12 miles round trip from Alum Cave trailhead, very steep), Charlies Bunion (8 miles round trip, steep), and Clingmans Dome via Forney Ridge Trail (10 miles round trip). These are for experienced hikers in good physical condition.

Backpacking is also available. The park has over 40 backcountry shelters and campsites. You will need a backcountry permit, which you can obtain at visitor centers or online through the park website. Permits are free but limited, especially during peak season. Backpacking trips range from overnight to multi-week journeys along the Appalachian Trail, which runs through the park.

What Wildlife You Might See and How to Stay Safe

Black bears are the most iconic animal in Great Smoky Mountains. The park is home to an estimated 1,500 bears. You may see them along roadsides or on trails, especially in early morning or late evening. If you encounter a bear, do not run. Back away slowly while facing the bear, and make noise to encourage it to leave. Store all food, trash, and scented items in your vehicle or bear-proof containers—never leave them unattended at campsites.

Other common wildlife includes white-tailed deer, wild turkeys, raccoons, and elk (reintroduced in recent years). Venomous snakes—copperheads, timber rattlesnakes, and cottonmouths—live in the park but are rarely seen. Watch where you step and place your hands when hiking, especially in warm months.

Streams in the park may carry giardia, a parasite that causes intestinal illness. Do not drink untreated water from streams. Bring your own water or use a water filter. Ticks are common in spring and early summer; check yourself after hiking and remove any ticks promptly.

Best Times to Visit Based on Weather and Crowds

Spring (March–May) brings wildflowers and moderate temperatures (50–70°F). Crowds are moderate. Some higher-elevation trails may still have snow in March and early April.

Summer (June–August) is the busiest season. Temperatures range from 70–85°F at lower elevations and 50–70°F at higher elevations. Afternoon thunderstorms are common. Parking and trail crowding are at their peak.

Fall (September–November) is the second-busiest season due to fall foliage, which peaks in mid-October. Temperatures range from 50–75°F. Roads and trails are very crowded in October.

Winter (December–February) is the quietest season. Temperatures range from 30–50°F at lower elevations and often drop below freezing at higher elevations. Higher-elevation roads and trails may close due to snow and ice. Winter hiking requires appropriate gear and experience.

What to Bring and How to Prepare

Wear sturdy hiking boots with good ankle support, especially on steep or rocky trails. Bring at least two liters of water per person, even on short walks. Pack a map or read offline maps on your phone—cell service is unreliable throughout the park. Bring a headlamp or flashlight if you plan to hike in early morning or late afternoon.

Weather changes rapidly at higher elevations. Bring a rain jacket and an extra layer even if the forecast looks clear. Sunscreen and insect repellent are essential. If you plan to backpack, bring a tent, sleeping bag, and stove. Campfires are not allowed at backcountry sites.

Check the park website or call ahead before your visit to confirm road and trail conditions. Some roads close seasonally or due to weather. The park website also lists current bear activity and trail hazards.
