If you’ve ever heard of the Great Smoky Mountains, you’ve probably heard of Clingmans Dome. Being the highest point in the most visited national park will grant you that kind of notoriety.

But with great fame comes great curiosity. Below we answer some of the most commonly asked questions about the this iconic landmark.

1. What is Clingmans Dome?

Clingmans Dome is the tallest mountain in the Great Smoky Mountains National Park.

It also has an observation tower, which was built in 1959 as part of the Mission 66 program, an effort by the National Park Service (NPS) to attract more visitors to national parks.

At the top of the tower (on a clear day), guests can see a 360-degree view of the Smoky Mountains, spanning over 100 miles.

2. Is Clingmans Dome in North Carolina or Tennessee? 

This is one of the most commonly asked questions about Clingmans Dome, and the answer might just surprise you.

Clingmans Dome is actually located along the state line, so half of it is in North Carolina and half is in Tennessee.

The visitor center is located on the North Carolina side.

3. How high is Clingmans Dome?

Clingmans Dome is the highest point in the Great Smoky Mountains National Park at 6,643 feet. This makes it the highest point in Tennessee and the third highest point east of the Mississippi.

Mount Mitchell in North Carolina wins the title of the highest point east of the Mississippi, coming in at 6,684 feet.

4. How difficult is the Clingmans Dome hike?

Clingmans Dome Road, which is open from April through late November, offers the easiest way to get to Clingmans Dome.

The road is a seven-mile drive and takes you right to the trailhead. From there, it’s a half-mile hike to the top of the observation tower.

This hike is considered moderate in difficulty. The road is paved, but the incline is very steep.

Unfortunately, according to the NPS, the trail to the tower is too steep to be wheelchair accessible.

Of course, if you choose to hike to Clingmans Dome during the winter, the hike becomes much longer and more difficult, but it is also less crowded.

If you hike it in the winter, be prepared for snowy or icy conditions.

Yes, Clingmans Dome is open year-round, including at night.

Though the dome is open year-round, Clingmans Dome Road closes in the winter and under certain weather conditions.

8. How is the drive to Clingmans Dome? 

Clingmans Dome Road is seven miles long and offers the most accessible way of accessing the tower (when it is open for the season).

The road is curvy but not terribly steep. If you are familiar with mountain roads, it will seem par for the course. It’s nothing like the Tail of the Dragon.

9. Why is it called Clingmans Dome?

According to The Origin of Certain Place Names in the United States, the mountain was called Smoky Dome by American settlers until the late 1850s, when it was renamed after Confederate general, Senator Thomas Lanier Clingman.

Some sources claim that Clingman argued that Smoky Dome was the tallest in the region.

It was later determined that Mount Mitchell was about 40 feet taller.

10. How is the weather at Clingmans Dome?

This, of course, is completely dependent on the time of year when you visit. But, keep in mind that rain and cold temperatures are very common at higher elevations.

In fact, temperatures at the top of the dome can easily be 10-20 degrees cooler than areas down below.

No matter when you’re visiting this observation tower, it’s smart to bring layers and a jacket, and be prepared for any type of weather.

Bonus tip: There’s a secret tunnel below Clingmans Dome

Did you know there’s a tunnel below Clingmans Dome that pre-dates the tower itself?

It’s a former hiker’s underpass most commonly known as the Thomas Divide Tunnel, but it is also occasionally referred to as the “Thomas Ridge Tunnel”, the “Old Mule Tunnel” or simply “The Hiker’s Tunnel”.

In the 1960s, the tunnel was cut off from the original trail, so you won’t happen upon it, unless you’re looking for it. 

It’s no longer part of any regular path or hiking trail and simply leads to a cliff with a beautiful view where the other side of the trail once stood.

  1. I have hiked to the top of Clingmans Dome tower 2 times and thoroughly enjoyed it both times. Wish I lived close by so I could hike it every day or at least more often. The last time I was there was on 11/6/2020. Arrived before sunrise to be able to see the beautiful colors. I feel so much “at home” there even though I was born in and have lived in Mississippi all my life. I look forward to going back as often as I can.

  2. No unfortunately I have not made it up to the top! When my parents took me there, we had went into the gift shop and they proceeded to tell us tht the wind chill was -3 degrees and I had not dressed to withstand tht temperature! It was perfectly sunny and clear but I was Frozen!

  3. The hikers tunnel is miles away from Clingmans Dome. It’s far closer to Newfound Gap

  4. Yes I climbed it several years ago despite my heart condition & getting out of breath I was glad there were resting benches. The air is very thin. It was an accomplishment for me but it was a struggle & almost had a panic attack. I looked down to the parking lot & the cars looked very tiny. There were several other people noisily discussing at the top so I waited to take in the beautiful sight after they left & coming down was easier.😎

  5. I have hiked up it many times over the decades. I was about 6 the first time, the concrete walkway spiral was new back then. (1959?) My last time was several years ago, about 2015 or so. Now, age & impairments he’s won’t let me climb it again. The view is spectacular, but often cloudy and the air polluted slightly. Winter views was best, I recall, on my honeymoon in February.

  6. My husband and I hiked to the Dome from Elkmont campground, a little over 15 miles, and had a shuttle pick us up in the parking lot at bottom of the paved trail to take us back to our tent. It was a memorable hike.

  7. We climbed to the top of Clingmans Dome and the view is not disappointing! Depending on your physical abilities I’d recommend for many to take plenty of water and make use of the benches to catch your breath on the way up.

  8. I’ve been up to Clingman’s Dome several times.. sooo beautiful 😍♥️!! I cannot wait until I can get back !

  9. Yes I hsve been there 4or5 times first was back in 86 and the last was 15 or 16 just about every time I’ve been there it was cloudy or hazy.This one time we were above the clouds and that was all you could see except for the tree tops below us.I hope I can get back at least one more time while I can still walk fairly good.

  10. I live in Sevierville on English Mountain and spend many nights in my truck in meditation and star gazing. Many bikes to the top and everyone is different. Very grateful to live in such a special place.

  11. Done both the paved and trail hikes to the top. I recommend the trails and I’ve been to the Thomas Divide tunnel…pretty cool

  12. I took my boyfriend there over 40 years ago he was from Mi. Had never been there later we got married he got out of the Marines started working for Fed. Bureau of Prison we would go back as often as possible we’ve walked in soon to be 11 times next trip. We love the Dome.

  13. Climbed it with my husband for our honeymoon, long walk for sure but the reward was well worth it. It felt so peaceful! We had our first kid a year later and plan on taking her when she’s big enough to walk herself.

  14. I have climbed twice in my life. The view is astounding and worth the effort of the climb.

  15. My wife and I hiked up Clingman’s Dome with our son and daughter-in-law on September 6, 2021 to pay tribute to her recently deceased father whose last visit to Clingman’s Dome was in 2019. He struggled mightily in the grip of ALS to make it to the top in 2019, but make it he did. Yesterday, the four of us toasted Irvin with his favorite libation, Makers Mark, at the top of the observation tower. We all miss you, Irv, may you rest in peace.

  16. What an awesome view. We were lucky enough the day we were there, a park ranger was there and told us it was the clearest she had ever seen. Peaks were seen she had never been able to.
