Clingmans Dome Information in the Great Smoky Mountains
At 6,643 feet, Clingmans Dome is the highest point in the Great Smoky Mountains National Park. It is the highest point in Tennessee, and the third highest mountain east of the Mississippi. The observation tower on the summit of Clingmans Dome offers spectacular 360° views of the Smokies and beyond for visitors willing to climb the steep half-mile walk to the tower at the top.
Clouds, precipitation, and cold temperatures are common at Clingmans Dome.Temperatures at the dome can be 10 -20 degrees Fahrenheit cooler than in the surrounding lowlands. In fact, the cool, wet conditions on Clingmans Dome's summit make the spruce-fir forest that grows there a coniferous rainforest. Dress in layers and be sure to bring a jacket, even in summer.
Although Clingmans Dome is open year-round, the road leading to it is closed from December 1 through March 31, and whenever weather conditions require. It's seven miles to the end of Clingmans Dome Road and there are scenic pullouts with endless views of ridges and valleys along the way. The road ends in a large parking area from which a 0.5 mile trail leads to the summit. The trail is paved but steep, and leads to an observation tower on top.
Besides the trail to the summit, there are several trails that start on Clingmans Dome Road and parking area. The Appalachian Trail (AT) crosses Clingmans Dome, marking the highest point along its journey from Georgia to Maine. The Forney Ridge Trail leads to Andrews Bald, a high-elevation grassy bald.
To get to Clingmans Dome, take 441 through the Park and turn off .1 miles south of Newfound Gap and follow the 7-mile Clingmans Dome Road to the large parking area at the end.
