Clingmans Dome Trail

The Highest Point in Tennessee

At 6,643 feet, Clingmans Dome is the highest point in the Great Smoky Mountains and the highest point in Tennessee. It's also the third highest mountain east of the Mississippi, after Mount Mitchell and Mount Craig in North Carolina. The iconic observation tower at the summit offers 360-degree panoramic views that, on clear days, can stretch up to 100 miles in every direction.

Don't let the short distance fool you—this half-mile trail is steep, gaining 330 feet on a paved but relentlessly uphill path. The high elevation means cooler temperatures (often 10-20°F cooler than Gatlinburg) and the potential for rain, fog, or even snow when lower elevations are warm and sunny.

Getting There

From Gatlinburg, take US-441 (Newfound Gap Road) 13 miles to Newfound Gap, then turn onto Clingmans Dome Road and drive 7 miles to the parking area. The total drive from downtown Gatlinburg takes about 45 minutes.

Critical Access Information

• Seasonal closure: Clingmans Dome Road closes December 1 through March 31
• Weather closures: The road may close temporarily due to ice, snow, or fog
• No overnight parking: The road closes at sunset
• Large parking lot: Still fills by mid-morning on peak weekends

A parking permit is not required at Clingmans Dome.

The Trail & Observation Tower

The paved trail climbs steadily from the parking area to the observation tower at the summit. While paved and accessible to most visitors, the steepness makes it challenging for those with mobility issues or cardiovascular conditions. Benches along the way offer resting spots.

The Observation Tower

The distinctive spiral observation tower was built in 1959 and rises above the surrounding forest to provide unobstructed 360-degree views. A ramp spirals to the top—there are no stairs. The platform at the top is small and can get crowded on busy days.

From the tower, you can see:

• Mountains of Tennessee and North Carolina spreading in all directions
• On exceptionally clear days, views can extend 100+ miles
• The Appalachian Trail, which passes directly under the tower
• Distant ridgelines fading into the famous Smoky Mountain haze

What to Expect

• Cold temperatures: Often 15-20°F cooler than Gatlinburg; bring layers
• Wind: The summit can be very windy; bring a windbreaker
• Fog and clouds: The summit is frequently in the clouds, limiting visibility
• Crowds: This is the most-visited spot in the Smokies; expect company
• Restrooms: Available at the parking lot
• No food service: Bring snacks if desired

Best Times to Visit

• Sunrise: Clearest views, least crowded, magical light
• Weekday mornings: Fewer crowds than weekends
• Late September-October: Fall color season and clearer air
• April-May: Wildflower season and spring clarity

Avoid the peak hours of 10 AM - 4 PM on summer weekends if possible. Also note that the famous Smoky Mountain haze is actually a natural phenomenon caused by trees releasing organic compounds—but pollution can make it worse, especially on hot summer days.

Combine with These Experiences

• Newfound Gap: Stop on the way for views from the state line
• Andrews Bald: 3.6-mile round trip hike from Clingmans Dome parking to a grassy bald with wildflowers
• Appalachian Trail: The AT passes through here—walk a section in either direction
• Forney Ridge Trail: More challenging hiking option from the parking area
