Nearly everyone who has visited the Great Smoky Mountains National Park is familiar with Clingmans Dome, located along the state line of Tennessee and North Carolina.

Completed in 1959, the Clingmans Dome observation tower is the highest point in the Smoky Mountains. It stands over 6,000 feet tall and offers 360-degree views.

On clear days, guests can see almost 100 miles in any direction from the top of the tower. Sadly, according to the National Park Service, air pollution usually limits the views to only 20 miles.

Still, it’s easily one of the most visited landmarks in the national park.

But have you heard of the secret abandoned hiking tunnel below Clingmans Dome?
