This is a great bike climb through beautiful scenery that only gets better the higher you go.  The start of the climb is conveniently located at the Sugarland Visitor Center in Great Smoky Mountains National Park, where there is no entrance fee.  

Why no entrance fee to enter a National Park? According to the Great Smoky Mountains National Park website, the land that now makes up this gorgeous National Park was once privately owned.  Tennessee, North Carolina, and local communities from both states paid to construct route 441/Newfound Gap Road, and this road was a major route crossing the southern Appalachian Mountains at the time.  It was important to authorities to maintain free and easy interstate transportation for local citizens, so, when Tennessee transferred ownership of the road to the federal government for the National Park, it stipulated that “no toll or license fee shall ever be imposed” on those traveling this road.  Hence, no entrance fee to this national park! (Great Smoky Mountains NP).

There are two tunnels -- one is about 30 meters long and we do recommend a tail light for this brief tunnel.

Clingmans Dome Observation Tower, constructed in 1959, is a 45-foot tower connected to a 375-foot sweeping ramp which visitors ascend to reach the tower’s observation deck.  Atop the deck, visitors are rewarded with 360-degree panoramic views from the highest point in the Great Smoky Mountains.  The tower itself is listed on the National Register of Historic Places, and is a major example of the National Park Service Modern architecture period.  The tower also represents the NPS’ Mission 66 program (1955-1966), which resulted in “a significant change in National Park Service planning, management, and architecture” and oversaw the construction of hundreds of buildings and structures, including nine towers.  Clingmans Dome Observation Tower served as a model for two later Mission 66 towers: Look Rock Tower (also in Great Smoky Mountains NP), and Shark Valley Tower (Everglades NP, Florida) (Clingmans Dome Observation Tower).

I walked my bike up and down the path without any objection . . .

more curiosity than anything from viewpoint hikers.

We are permitted to ride to the parking lot at the end of Clingmans Dome Road, but not the 0.5 miles from the Clingman’s Dome observation tower.  There is a bike stand to lock the bike at if you bring a cable and lock with you.  Otherwise, you will probably be ok walking your bike round trip from the parking lot to the observation tower.  

The National Park Climgman’s Dome page advises:

Pets and bicycles are not permitted on the paved trail to the observation tower, or on any other trails in the area. A bike rack is located near the beginning of the paved trail to park bikes while walking to the top. You will need to bring a lock with you to secure your bike (More).

Ride summary by Dan Razum of Campbell, California:

The route is straightforward with the first 13 miles are on route 441.  This section is on beautiful pavement but carries a lot of traffic with no shoulder.  For perspective, I did this climb in early May on a weekday and was passed by a car every couple of minutes.  If you do this in the summer on a weekend, the traffic will make it almost impossible to enjoy this ride safely.  After 13 miles on 441, turn right for Clingmans Dome for the next seven miles which will take you all the way to the top. These seven miles, which are also on great pavement, give you beautiful views of the park and carry about half as much traffic as route 441.  Around mile 17.5, you will get a mile stretch that is flat-to-down, giving you a nice reprieve before tackling the final stretch of this climb.

 

The top of Clingmans Dome has a large parking lot where visitors take a half-mile trail to the circular dome that offers 360 degree views of all the surrounding mountain ranges.  Please note this last half-mile is a 10 foot wide walking path that has lots of people coming and going.  Although I didn't see a sign that specifically said no bikes, the ranger said it isn't allowed as it would be impossible and downright unsafe to do this with all the foot traffic.  If you want to do this last stretch, which is very steep (around 14%), you would need to do it very early in the morning or right before sunset.

Steepest quarter mile begins at mile 20.2 (13.5%) and mile at 19.8 (8.1%).
